Very frustrating mail problem

**t_ras** · May 1st, 2008

AMD 64, Kubuntu 7.10, Postfix 2.5.1. using ISPconfig to configure users.

I have a very annoying problem. I accidentally deleted a users home dir (through sudo...), for a user created through ISPConfig.
I wanted to recreate the user so I removed it from users\groups, but ISPConfig wouldn't let me to recreate it, claiming it already exists.
I tried recreating it through users/groups and it worked fine (but that has its own mailing issues when working with ISPConfig...). So I understood it is ISPC problem. I created a user with a different name and then change its iname in ISPC tables, Users/groups, homedir. After getting rid of procmail and forward files created by Linux (ISPC creates its own), I managed to send mail (which actually reaches the sent mail folder), but I can't get mail.
For other users created directly from ISPC without changes I do get mail.
Also - nothing wrong in log!

I tried reemoving the manual entries, but it didn't help.

tried also adding manually -terrenis.net.

It is very frustrating, since I'm getting no errors...

Any ideas?

Hmm, the origin of the problem is likely that the newly created user now has a different UID from the old user account. So you can fix it by looking at the mail spool and changing the ownership of the mailbox (probably in /var/spool/mail) or by changing the UID of the user back to what it was before.

Cheers,

Herman

In deed there where two boxwes there with the same owner but two diferent names. changed the owner fo one of them to something else and now ther is one box with owner "martin" and the homdir of martin where martin is owner.
I can see the mails reaching the box in /var/spool/mail, but yet they dont reach my inbox....

**HermanAB** · May 1st, 2008

OK, the command 'ls -al' will show all the file attributes.

The command 'chown username:username filename' can be used to reset the ownership of the mailbox.

Look at the error logs in /var/log/mailsomethingorother to see what is going wrong with 'tail -f /var/log/mailsomethingorother', then send a message to see what errors and warnings pop up.

Sadly all seems to be fine in logs (apart for Clamav being an old version)
This is what I see in log when receiving a mail:

Code:

It reaches ls -la /var/spool/mail/martin box
for which permissions are:

Code:

A tried changing owner to www-data also - no can do...

Thanks for all the help pal!

I haven't read the detail of this thread but try repeating the above ls tests with the -n flag in order to show numeric user/group IDs. It may be that your old 'martin' is not the same as the new 'martin' as far as the system is concerned. if you have any old files that were definitely created by the old 'martin' then check the ID of that file owner too.
