Local emails go into black hole after user is renamed

[windserve]

After renaming a local user from username to username1 using /usr/local/directadmin/scripts/change_username.sh, I'm unable to send emails from addresses on that account to any other accounts on the server. Every other combination (emails from that account to external ones, emails to that account, emails between other accounts on that server, etc) are working.

Are there any ideas on what could be causing the problem? I've disabled SpamAssassin just in case, and looked through all the files in /etc/virtual/ and /etc/virtual/username1/. Nothing is sticking out at me as being the likely cause of the problem.

After I changed the username, I did have to restart sshd to get SSH logins working for this account. Do I need to do something similar with exim? I tried restarting it, but that didn't do the trick either.

Here's what /var/log/exim/mainlog shows:

2008-07-27 16:15:27 1KNDaR-0005vD-F3 <= [email protected] H=localhost (web01.windserve.com) [127.0.0.1] P=esmtpa A=login:[email protected] S=810 [email protected] T="5:14 webmail test" from <[email protected]> for [email protected]
2008-07-27 16:15:27 1KNDaR-0005vD-F3 => me <[email protected]> F=<[email protected]> R=virtual_user T=virtual_localdelivery S=927
2008-07-27 16:15:27 1KNDaR-0005vD-F3 Completed

/var/log/exim/rejectlog doesn't show anything for the disappearing emails. This happens with both Squirrelmail and Thunderbird sending the emails.

Thanks,

Matt

This is interesting. If I use telnet to try to manually send an email from the problem domain, it gets delivered:

[root@web01 conf]# telnet localhost 25

This turned out to be a Thunderbird issue. I noticed that emails being sent from the renamed domain are being delivered to the proper Maildir. If I login to Squirrelmail or UebiMiau, the emails show up. I tried a fresh install of Thunderbird on another system, and they started showing up, so I deleted/recreated my Thunderbird profile on the original system and...now everything works.
