Troubleshoting E-Mail Problems

I'm trying to access my email but am getting the error "this user has no $HOME/Maildir"

Try restarting the pop3 service.

[root@iworx ~]# service pop3 restart

I just opened a new smtp port on my box but I can't seem to connect to it?

Make sure you opened the new port in the firewall if you are running one. Also make sure your email software (Outlook, Eudora, Thunderbird, etc.) is set to the correct port. If you don’t specify one these programs default to port 25.

Outgoing SMTP email does not work but incoming mail works just fine. What's going on?

Most likely the ISP of the email sender is blocking subscriber access to port 25 (the SMTP port) for all but their own mail server as an anti-spam measure. Unfortunately there is no way around this other than setting up your SMTP server to accept another port IN ADDITION TO port 25 (changing your SMTP port to another port number will make it worthless as a mail server since SMTP servers use port 25 to communicate with EACH OTHER as well).

Fortunately, InterWorx-CP has enabled a secondary smtp port (default 587) which has to be enabled on NodeWorx on the System Services => Mail => MTA Settings screen.

My server sends mail saying it is InterWorx-CP SMTP Server. Can I Change this to something else?

Yes, edit the SMTP Greeting setting on System Services => Mail => MTA Settings in NodeWorx

or, edit:

/var/qmail/control/smtpgreeting

from the shell.

Why does mail stay in my email queue?

Sometimes messages can’t be delivered immediately (e.g., problems with the receiving mail server) so the delivering server will queue the message and retry later. Once the max amount of tries is hit (default is a week), the email will be removed from the queue (i.e., the server will stop trying to deliver it). You can adjust the queue lifetime using this howto document.
