Unable to chdir to maildir. (#4.2.1)

[mweber]

Hi,

we do have a quite serious and strange problem with the psa-qmail on Plesk 8.2.1 on a SuSE 10.1 Root Server.

One of the Domain do not receive any E-Mail. All the Sender is getting back:

"Hi. This is the qmail-send program at s15299087.onlinehome-server.info.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<testuser@example-domain>:
Unable to chdir to maildir. (#4.2.1)

This domain have a redirection to another domain, it's just made for the Mailadresses.

So i thought "permission problem" and checked that. There is no difference to the other domains, which work fine.

So all (and i checked that 3 times carefully) permissions for all the domain.xyz directorys under /var/qmail/mailnames are equal (popuser,popuser - rwx------). Same goes for the username subdirectorys (popuser,popuser - rwx------).

Content of .mail-default file is the same in all directorys too.

All Domains are properly in the

/var/qmail/control/rcpthosts
/var/qmail/control/virtualdomains

files. spamfilter is disabled, system wide, and there is no other 3rd part software running.

In /usr/local/psa/var/log/maillog it looks like this:

... qmail-queue-handlers[13460]: Handlers Filter before-queue for qmail started ...
... qmail-queue-handlers[13460]: from=sender@domainname
... qmail-queue-handlers[13460]: to=receiver@problem_domain
... qmail-queue-handlers[13460]: hook_dir = '/var/qmail//handlers/before-queue'
... qmail-queue-handlers[13460]: recipient[3] = 'receiver@problem_domain'
... qmail-queue-handlers[13460]: handlers dir = '/var/qmail//handlers/before-queue/recipient/receiver@problem_domain'
... qmail-queue-handlers[13460]: starter: submitter[13461] exited normally
... qmail: 1215139906.173175 new msg 12648047

... qmail-local-handlers[13462]: cannot reinject message to 'receiver@problem_domain'
... qmail: 1215139906.188819 delivery 23470: failure: unable_to_chdir_to_maildir._(#4.2.1)/

skipped the notifying of sender part ...

So i am quite clueless cause:

- all other domains work fine
- all directory permissions are okay (checked three times at least)
- qmail does his job perfect
- the // are not the problem, logiles show them for all the entrys (still working fine)

Any input would be highly appreciated cause i have no ideas how to approach the problem anymore.

regards,
Michael

after a bit more looking around i made some new adresses for this Domain

'ls -l' shows the following:

drwx------ 5 popuser popuser 72 Jul 4 19:04 user.name
drwx------ 4 popuser popuser 52 Jul 5 09:13 system.test
drwx------ 5 popuser popuser 72 Jul 4 19:04 another.user

and the 'system.test' adress do work!
