This is my first attempt at running postfix, or any
email server for that matter. I have it installed and
running on redhat 7.3. Installed from source. I did
specify a few things so its not completely default.
The only thing I actually changed was where the
queue's are. I put them in /usr/postfix/queues. I have
since moved the queues around and updated such
information in main.cf but the mail never makes it to
the mail box. It is accepting mail and I turned on
soft bounce and I get the following message in the
defer queue

"<matt@gfccall.int>: cannot access mailbox
/user/postfix/queues/matt for user matt. cannot create
file exclusively: No such file or directory".

Matt is the account name I'm trying to send the mail
to. gfccall.int is the domain. The mail servers name
is red_box. MX records are working correctly, like I
said I know mail is getting to its just not getting to
the users mail box. Do I need to have the queues in
any special location, or is there something else that
I'm missing?

Thanks in advanced for any help.

Is there a reason for making changes?

If you just use the default install locations it is more likely to work right. Changing things can make for unforseen problems.

Maybe the subfolder is not there or has incorrect permissions.


anyway try this..


/etc/postfix/post-install create-missing


also I would recommend /var/spool/postfix

That's where stuff like this is supposed to go on a unix system

Thanks for the help.

I found the problem late yesterday. I didn't specify the mail_spool_directory in my main.cf. The reason I moved the postfix queues around is because I partitions my HD like a newbie and so things are a little tight on space right now. Its just a test bed server so I'm going to re-install and do it right this time. :-)
