Well Please try to not laugh too hard from my lack of knowledge in this area. Also don't know what my real problem is so I can't say I am in the correct forum.

How do I know if Courier is working? IE I can telnet into my Map using
telnet domainname 143 and it says "Courier Imap ready".

I can send an email to user@domain.com and it doesn't get rejected but it sends it to my gmail account (I don't know I must have set this up as the admin address or something during my 6 hour install, 3 times).

I can set up an account imap and check messages in thunderbird at work. I get "unable to open this mailbox"

So basically I don't know what is working and what isn't and where to start the trouble shooting.

Hope this makes some since to someone....

Thanks
Thom

The imap problem is related to your roundcube problem, no directory with mail in it. Look at that post for an answer.

For the sending problem can you post the output of the command:

postconf -n

It shows the configuration of your mailserver

Also if possible post the part of /var/log/mail.log where the actual error occurs of the sending.
