[imp] Very strange login problems.

[William Tucker]

Hello,

First a quick rundown of what we're running:  horde 2.0, imp 3.0, apache 1.3.24, php 4.1.2, UW imap IMAP4rev1 2002.334, solaris 8

On to the problem.  I have a user that has been using webmail for quite a while.  Starting last month, when she logs in, she is authenticated as a completely different user.  This happens about 90% of the time.  It is not the same user every time, and it's not consistent.

Also, in her inbox, she has an email that is not intended for her.  This email is a reply to an email apparently sent from her account.  I thought it was just a forged/broken header, where the From tag got somehow mucked up, but when I checked her sent-mail, the original message is in there!!  So somehow other users are getting authenticated as her, and sending out emails, and all she's getting is the reply.

Has anyone else ever seen behavior like this?

Thanks in advance,
