One of three mail domains slow and delaying transfers

Question

One of three mail domains slow and delaying transfers

I have three mail domains on my server. I recently added the third domain and it is very slow and most of the mail is getting put into the deferred queue.

As far as I can tell all the user and domains are configured exactly the same.
user x gets mail on abc.com domain
user y gets mail on ghf.com domain
user z gets mail on mno.com domain <-- this one is the problem
all hosts go to the same IP and resolve correctly. mail is configured for all domains in the same way.

I've upgraded to apache 2, php 5, and setup roundcube web mail. I've only tried IMAP for the accounts checking with apple mail and the web mail through roundcube and the newest account is the only one having problems.

outgoing mail seems to work fine but incoming ends up on the deferred folder. I've issue 'postfix flush' and it still ends up back in the deferred queue.

x server g5, Mac OS X (10.3.x)

did you update your alias maps and run newaliases ?

check logs for errors
verify local recipient maps

yes I did update aliases and run newaliases
no errors

can you provide a bit more detail on 'verify local recipients map'

I've just followed the same process which I have done many times in the past. To add a domain and mail for the domain. Just this one is failing.

Impossible to help without seeing log entries. Please make sure the logging level for SMTP and IMAP is set to "Information".

Then please send a testmail from the outside to the affected domain and follow it through the logs. Post relevant extracts.

I also saw this after doing a restart not sure if this was just a problem during start of the mail service or relates to the underlying issue.

" couldn't connect to lmtpd "

postqueue -f

watch tail -f /var/log/mail.log

where is your user information ? LDAP local master or local Replica, or on another machine?
it seems although Im not seeing a 550 errror code, that your system doesn't know userx.

can that user log into mailserver ?

finally got it working
here's what I ended up doing (most done through admin and workgroup manager)
1. stop mail service
2. delete the user account
3. recreate the user account (different full name and initial short name)
-- used open directory auth
-- set mail mail option to smtp with server set accordingly
4. added short name the same as previous (matched /var/spool/user/[shortusername]
5. removed any aliases for the account from /etc/postfix/aliases (user name and short names are the only ones which will be used so no need for aliases)
6. restarted mail
7. ran newaliases, postalias..., postfix flush

check both apple mail and web mail (roundcube) and all is good. (now if someone would help with my ssh problem....)
