I was having a tough time with this type problem myself. My setup is as follows: Mercury/32 v4.52, SquirrelMail v1.5.1 (1.4.15 worked ok too) on IIS 5.0 [SquirrelMail is separate from my Mercury/32 server], PHP 4.3.4 and NetWare OES 6.5.6 storing messages. SquirrelMail is run from a virtualized directory of C:\MAIL and PHP is located in C:\PHP.

I found out the hard way that the PHP.INI must have fastcgi.impersonate = 1 and that the redirect.php from v1.4.15 of SquirrelMail make this work well. I even have the address_add plugin working (not under v1.4.15, though). I highly recommend using the autosubscribe and folder_sync plugins also. The documentation for this is very poor and that made for lots of trial and error to get this going...

HTH 

I've been dabbling with webmail off and on since something like 2003.  Captaris Webmail works fine but its discontinued and I've outgrown the 25 user license.  Also, Captaris lacks a much needed search feature.

The last couple of weeks have gotten me to the point where I have SquirrelMail running on Apache with Windows 2000 Professional as the O/S.

 Using either Pegasus or Captaris I can look at my mail folders and see "Copies to self 2000" through "Copies to self 2007".  Using SquirrelMail, I see "Copies to self 2000" through "Copies to self 2003", with "Copies to self 2004" through "Copies to self 2007" conspicuously absent.

Does anyone have any suggestions on where I should begin looking for the problem?

And not to confuse the issue, but with Captaris the login is username/password.  With SquirrelMail its username@domain.com/password.  What's up with that?

Not sure where to start looking but the first place I would look is in cache.pm  I've used SquirrelMail for years but I'm running the v1.5.1 since it does caching better than 1.4.x.

I use a simple username and password login via SquirrelMail.  Are you sure you specified a domain? Check out you settings by running the config.pl.  Here's what I have in the server setup.

 SquirrelMail Configuration : Read: config.php (1.4.0)
---------------------------------------------------------
Server Settings

1.  Domain                 : tstephenson.com

S   Save data
Q   Quit
 

I'm using SquirrelMail v1.4.11 as I was unable to find a suitable download of 1.5.x for Windows.

One thing I noticed right off the bat from your configuration is I'm running SM/Apache on a separate machine from Mercury/32. 

 With cache.pm don't you just delete this file and let Pegasus recreate it?

The separate machine is no big deal as long as we're talking about a local lan.  Yes, the cache.pm will be re-created when deleted.

This SquirrelMail 1.5 which your using, is it the 1.5.1-20060409 on the http://www.squirrelmail.org/download.php page?

Nope, that's the translations only.  It appears they have changed things, the v1.5.1 was located right next to the 1.4.x release where now you see a pointer to the SVN.  Appears they now want you to do the SVN download.  I've gotten updates in the past using CVS but never via Subversion.

Thomas, 

I've upgraded from 1.4.11 to 1.4.14[SVN] (after a quick review and rejection of 1.5.2[SVN]) and deleted cache.pm to no avail.  I'm still missing folders in Squirrelmail.  In Pegasus I count 416 folders.  (Yes, I'm a pack rat)  In Squirrelmail I'm counting 225.  That sounds almost like I'm running into some size limit set in the system.

Might also mean that SquirrelMail does not see all the folders as registered folders.  Have you looked in the folder view to ensure all the folders you want to look at have been subscribed?

That was the problem!  (But I wonder why not all were subscribed by default?)

The current version of Squirrelmail has pre-defined settings for Mercury/32.  I'm changing the Trash folder to "Deleted Messages" and the Sent folder to "Copies to self".  Does anyone see this causing a problem?

When I send a message to Pegasus from Squirrelmail, the date displays fine.  When I send a message to my SpamCop email address, the date in the SpamCop Inbox view shows "Unknown Date", however the date displays fine when the message is opened.  This does not happen when I send a message from Pegasus.  Does anyone have any idea what is causing this?  Here are the headers from two messages in my SpamCop Inbox:

Date:       Sat, 16 Feb 2008 13:16:33 -0500 (Eastern Standard Time)
Date:       Fri, 15 Feb 2008 11:15:54 +0000 [02/15/2008 06:15:54 AM EST]

The first line is the Squirrelmail message, the second is from someone else and displays correctly in Inbox view.  I assume the problem is with the () vs the [].  Is this something that I can change or do I need to contact the Squirrelmail team?

File this one under "Things that make you want to get on all fours and bark like a dog".

So, I've got SquirrelMail more or less working and I want to start adding users to the system. 

The first user I add has a 4 digit username - XRAY.  Now, up to this point I've been logging in as username@domain.com and its been working fine.  I go to log XRAY in and I get a "Unknown user or password incorrect" error.  Doh!  I run dsrepair.  I reset the password.  I doublecheck the popalias "xray = xray.ou.o".  Nada.  Then I check the Mercury/32 screen and I see I'm getting a password failure.  Something else also catches my eye.  The other users are showing up in the IMAP window as "username.ou.o" but poor 'ol XRAY is showing as "XRAY@domain.com".  Humm.  Having tried everything else, I create a new account XNRAY and guess what?  The system works fine with the 5 digit username.

Somewhere the login is not being parsed correctly.  It could be: SquirrelMail, Apache, Windows 2000, the Novell 4.90 SP2 client, or Mercury/32.  Take your pick.  For the present time, I'm going to avoid creating 4 digit usernames by adding a middle initial.
