I broke postfix on a production server

[godsdog]

Hi. I changed IP information for a virtual domain on my server last night to an external IP and changed MX records to suit. I also changed the mailserver setting to external while playing around with an physically separate server.

Today I realize that mail is building up in user folders (eg: /home/www/web1/user/admin/Maildir/new) except mail clients (including IMAP & UebiMiau) fail to recognize any mail at all. I have since removed that domains DNS records and complete site from the server and reboot to no avail.

Please help...spanx.....

[godsdog]

<blush> I just remembered that I had a catch all email account on another domain forwarding all email to a catch all account on the domain that I moved/deleted/messed with. It seems that because mail wasn't being forwarded, it locked everything else up.

[godsdog]

But mail is still stuck in the new folders for everyone...back to searching the forums....

[godsdog]

It seems that mail being sent to a deleted account (even removed from Recycle Bin) is still trying to be forwarded to another Mail Server IP...

(BTW: I find the following commands very handy...)

postsuper -r ALLThen check your mail log with

tail -f /path/to/maillog

[till]

It seems that mail being sent to a deleted account (even removed from Recycle Bin) is still trying to be forwarded to another Mail Server IP...

Is the deleted account still listed in /etc/postfix/virtusertable?

[godsdog]

HI till, thanx for the response.

It wasn't until I recreated it. I think what I saw from using tail -f /var/log/maillog was stuff queued up from before. It kept saying 447 messages queued up. Now it says 1

I'm back to square one now with mail accumulating in the new folders of everyone's mail dirs. I think something else has frozen up...

[godsdog]

I think I'm stuck. When I connect to any account via IMAP, I see amongst various mail folders a dir named Maildir. Under that is new and then each mail message apears as a folder. What's going wrong here? I tried a reinstall of ispconfig to no avail. Please help.

When I send myself a test email, here's the tail of maillog

Just checked dnsreport.com and was given the following warning...
mail.bcsolutions.ca claims to be non-existent host localhost.localdomain:
220 localhost.localdomain ESMTP Postfix
I didn't change my hostname...more digging...

[godsdog]

Okay, I've changed my hostname...still mail keeps building up in each users new folder. Calls from my clients are driving me nuts....

Well, I guess if I wanna have email back up for tomorow, I best get backin' up and reinstalling. I'll definitly know better next time than to go messing around with DNS settings for virtual domains on a server I can't afford having downtime on.

I'm starting to think that this problem might be worthy of a bug report. All I did was take an existing domain that I was using on my local server running the latest upgrade of ISP Config and change it's records to point to a new address. I also set up it's mail config to external. I don't have a test server to duplicate results and I've reinstalled from scratch so...
BTW: I ran a backup of all domains checked everything except for logs, and not 1 single peice of mail was xfered from my IMAP users...Are there improvements slated for the backup function? Maybe I should stop complaining...maybe plesk spoiled me...(btw: I forgot to backup ispconfig's own database...lol you probably hear from people like me all the time.) Oh well, I'm totally commited to ispconfig now and am planning on converting other companies I admin for.

Do you use Maildir or mbox?
