Bugs in Merce source code
1. Fix the formatting of vacation message reply. Replace the
  string
```
      <TEXTAREA Name=msg ROWS=3 COLS=30 ALIGN=left> __MSG__
      </TEXTAREA>
      
```
  by ?
2. Modify /opt/merce/lib/template/remindme/remGinder_help.tmpl
  replace all: @@NET_DOMAIN@@ with the organization domain name of the Merce
  server.
3. Fix the bug of user edit - it shows "unable to update aliastable"
  if a user has an alias of type 'U' and one or more aliases of type 'A'.
  This error is because of incomplete where clause in update query.
  This bug can be fixed by inserting following line at line no: 292 of
  /opt/merce/bin/usr/useradm_dat.pl
```
      push(@$where, " aliastype = 'U' ");
      
```
  NOTE: please verify the above line should be just after the following
  block of code.
```
      $form{'aliastype'} = 'U';
      if (! $flag) {
      undef $where;
      push(@$where, "emailaliasto = " .
      Relation::User::quote($dbh, 'intranet_id',
      $form{'intranet_id'}));
      push(@$where, " aliastype = 'U' ");
      
```
4. Mfilter should do case insensitive checking of sender and
  recipient.
5. When user is edited and email-id filed on user edit screen is
  modified it does not reflect in preference file of user for
  squirrelmail.
6. Add Netdomain variable in /etc/merce/Siteconfig.sh
7. Check squirrelmail, ldap aliases scripts for patching with
  Netdomain and Netorgdomain
8. Remove the functions isadmin_local, isadmin, is_otheradmin,
  is_anyadmin and have one function which checks for administrative
  privileges. Call it is_admin.
9. Fix the formating of vacation message reply
10. Change the message on the welcome page of admin
11. Change the message in title bar of Mtracks admin page
12. mail_user function of /opt/merce/common/lib/perl/Utils.pm
  should return 1 for unsuccessfull execution. Currently it prints to
  STDERR.
13. licencechk, servicechk, sysinfo, syschk(compiled shell
  scripts) become zombie randomly. For now we have compiled these shell
  scripts with -T option for 'shc' utility.
14. Sometimes user edit gives error 'Unable to update rows into
  table - aliastable' on browser. Because in useradm_dat.pl, it does not
  check ' aliastype = "U" ' in 'where' caluse while updating aliastable
15. # Installer ask question of domain name during installation. It
  does not take domain name starting with numeric values like 2coms.com.
  So the reqular expression should be modified in questions.list
16. Integrate new cleantmp script with Merce
17. Create the user junkmail on master during installation time.
18. Alias file(/etc/aliases) becomes corrupted due to some
  unknown reason. The RHS entries in the alias files are removed.
19. To add $Netdomain variable in /etc/merce/Siteconfig.sh
  and to check squirrelmail, ldap, aliases scripts for patching
  with NetDOMAIN and Netorgdomain
20. When "adding" user, mtracks correctly displays "Date of
  Joining" year from 1937-2007(Current) but while "editing" the user
  info, the year in "Date of joining" starts from 2007.
21. Funny choice of words and incorrect English in the questions
  asked by the installer. Cosmetic changes - text needs to be fixed in the
  installer config file.
22. During user deletion a users mailbox is deleted without
  taking any backup of his home directory or mailbox. Shuvam's script
  which takes a backup of the user's mail and home dir area should be
  integrated with the user deletion script. This backup should be deleted
  once in 6 months or 1 year by cleantmp script.
23. The script which takes backup of user's mail and home is - apps1:/usr/local/sbin/userarchive. It needs to be integrated with merce. The script may not work for all flavours of Linux. This script, in its current config, assumes that there is one level of subdirs in the IMAP
  spool area. If Cyrus is configured to keep /var/spool/imap/s/saurabh
  then this script will not work.
24. The file /opt/merce/lib/Filesendrecvconfig has incorrect entry for
  httpdupload on slaves. It is incorrectly spelled as q.*.httpupload*
  instead of q.*.httpdupload*
25. xbackup script should take a configuration file as a parameter on the command line.
26. xbackup script should prepend the timestamp in output file and append the status "done" upon completion.
27. If there is an alias pointing to only one email address and that email address is removed (removed not deleted) from the alias list, the alias should get deleted but it stays and in the alias file the entry: "testalias: saurabh@starcomsoftware.com" changes to "testalias:"
28. When we run licencechk it gives error of 'Illegal
  division by zero' error. The licecnecchk uses
  /opt/merce/sbin/sysinfo internally.
  The reason of this error is:
  sysinfo uses output of `free -m' and greps the corresponding values
  of 'Mem:' and 'Swap:'.
  The percentage of Swap used is calculated in sysinfo.
  
  When Swap area is not created, it not appears in `free -m' output.
  and it shows the 'Illegal division by zero error while calculating
  percentage' of Swap used.
29. Snippet from a mail of Deepak - cause not known. He will replicate and give more info.
  There was one thing I noticed while deleting aliases using UI, If I select two aliases for eg.
  prachitee.naik: prachiti
  prachitee: prachiti
  
  I got an error saying the task could not be completed. And when I search again using UI for those aliases both aliases were deleted. But when I checked in /etc/aliases file one of the aliases did not got deleted in the above example prachitee: prachiti
30. To check the variable names in Netconfig.sh and other scripts in
  /opt/merce/bin/ which uses NetMailgateways, Netsmtpservers etc
  interchangeably .
  Each scripts must be using proper name.
31. Default preference file is not created for mailbac user at
  installation.
32. /opt/merce/bin/usr/clientadm_edit.pl does not patch country.
  country code IN is hardcoded. put $::Netldapconuntry
33. modify /opt/merce/bin/cron/usrusage_report to replace following lines
  replace
  homedir_info=`df $HOMEDIR | grep -vE
  wih
  homedir_info=`df -P $HOMEDIR | grep -vE
  replace
  imapdir_info=`df $IMAPDIR | grep -vE
  with
  imapdir_info=`df -P $IMAPDIR | grep -vE
34. Check all the script which are vulnerable to SQL injection.
  For example: alias editing UI has a bug. Giving '%' in search
  give all the aliases in database. In this UI the query should have
  been prepared and then executed.
  Check all the script to ensure that all queries are prepared and
  executed so that special charecters are escaped by SQL.
35. "mtracks" is not patched in the zone file of Netdomain and Netorgdomain but it is present in /etc/mail/local-host-names
36. The alias entry in alias file become wrong when the user edit his
  details from 'user' -> 'user database' -> 'employee' link on
  Mtracks/Merce UI and when the user has his intranet ID in
  other aliases.
  For example the user 'abhay' is in 'netsupport' alias. This will
  have entry in database as aliastype = 'A'. It should delete the
  entries of aliastype U only. But this check was not done in code
  of /opt/merce/bin/usr/usergen_dat.pl. So many times it deletes
  modifies the aliases of alias type A in alias table.
  
  To fix this bug
  search the following lines in /opt/merce/bin/usr/usergen_dat.pl
  
  $fields = ['emailalias'];
  push(@$where, 'emailaliasto = ' .
  Relation::Aliastable::quote($dbh, 'emailaliasto',
  $form{'intranet_id'}));
  
  Add follwoing line after these lines
  push(@$where, " aliastype = 'U' ");
37. aclctl should use /etc/applyacl.cf to do chown, chmod of shared area.
38. aclctl should do setgid to group having no members to the shared areas.
39. Mfilter changes '<>' from address to 'MAILER-DAEMON@domainname'
  It should change the '<>' to 'MERCE-ADMIN@domainname' or
  'UUCP-ADMIN@domainname'.
  Mfilter should never user 'MAILER-DAEMON@domainname'
40. Some times event_handler in merce runs continuously and
  increases the load average of merce server. This happens
  when there exists a file which is not being used by any
  program and which event handler will not process.
  for example: there is a qfile in /opt/merce/update/pending dir
  with name q.1190614216.useradd.30943.addsmbuser_mas.
  event_handler will not process it and keep looking for next
  file without sleep.
41. Add script to clean up the reported_event table every 15days
42. When a website is blocked at master location, it is not reflected at slave location. This is because /opt/merce/bin/maint/proxyblock_activate tries to copy the proxyblock file to /opt/merce/tmp where user 'mercexfr' does not have write access.
43. Bug in user deletion. When user is deleted, all the entries for
  deleted user are removed from alias table. But from alias file
  only user's email ID and intranet ID are removed. So user is
  not deleted from the aliases in which he/she was added from UI.
44. Remindme bug: remindme trims the long subject lines.
45. /opt/merce/bin/filesend program creates some Xdifffiles.tmp.XXXX
  files in outgoing/servername/ directory. These files should be
  automatically removed. Also need to check why these files are
  created?
46. Alias editing shows a row with 'alias' in it when some alias entry
  is removed(on confirmation page).
  To solve this problem add following:
  if ($param eq "alias" ) {
  $hidden .=
  "< INPUT TYPE='HIDDEN' NAME='$param' VALUE='$form_cp{$param}'>";
  next;
  }
  
  after the give line below in opt/merce/bin/usr/useralias_addremove.pl
  if ($param eq "SUBMIT") { # or $param eq "alias") {
47. The /opt/merce/lib/perl/Queue.pm does not allow a program to
  generate multiple qfile from same process at same time.
  To solve this problem modifiy the Queue.pm to do following:
  if(not defined global-ts-var) then
  global-ts-var = current-ts
  else
  global-ts-var = global-ts-var + 1
  
  and the get_qfilename function in Queue.pm will return the
  qfile name of the format q.$global-ts-var.$event.$pid
  
  The above will take care of generating multiple qfiles from same
  the program.
48. Change the formating of the text in HTML page titles:
  for example currently on main admin page of Merce it shows:
  "MERCE - the complete Network tracking systems"
  It should be:
  MERCE - Messaging and Enterprise Resource Control Environment
Improper configuration.
1. Check the configuration for logrotate in RHEL4 and SLES10 for
  the support of maxage, dateext, bug for size rotation and decide on a
  criteria for log rotation
2. Amavis stops periodically because the current /etc/amavisd.conf
  is old and has not been configured as per the new configuration scheme.
3. Mails from junkmail@organization.com should not be checked
  for spam.
4. php.ini imposes limit on memory_limit (8 MB), upload_max_filesize
  (2 MB), post_max_size (8 MB). Decide what should be these limits
5. Every shell script in the MercE source tries to source
  /etc/merce/Netconfig.sh. If this file is not found it tries to log an
  error message with facility local3 and priority emergency. There is no
  entry for local3.emerg in /etc/syslog.conf. Add an entry in
  /etc/syslog.conf for local3.emerg.
6. all scripts which are cron jobs of merce should be in /opt/merce/bin/cron. cleantmp should be in /opt/merce/bin/cron instead of /opt/merce/sbin
7. In squirrelmail's configuration file value for smtp server is "localhost" and value for imap server is also "localhost". SMTP server should be "smtp." and IMAP server should be "imap.". We need to add this to installer.
8. update config file /etc/sysconfig/syslog with current version of
  syslog package in RHEL4 Update5.
  For now we have to add SYSLOG_OPTIONS variable in
  /etc/sysconfig/syslog variable in /etc/sysconfig/syslog variable
  to enable network logging in syslog.

Cyrus Perl Module

Submitted by jignesh on Mon, 2008-01-07 11:22.

Include new perl module IMAP::Admin instead of Cyrus::IMAP::Admin as the later is now unavailable on even CPAN. Also the following scripts needs to be modified to use the IMAP::Admin module: addmailbox.pl, delmailbox.pl.
