Not 100% sure what you mean by this, however:
- Messages would be received and delivered into mailboxes on the server
under the control of Exim
- Courier would be used to access the mailboxes from a client
As such, the problem would be with Exim rather than Courier. When you
say that mail delivery works from the CLI, do you mean the equivalent of
(to quote the FAQ you refer to):
nebula:/home/jasonb# echo "my test" | mail -s "test message" jasonb
It may be the case that mail delivery works "within the machine", but
inbound messages from other hosts on the network are being rejected. I
suggest running "dpkg-reconfigure exim4-config" again and ensuring that
the correct option is selected, or editing any ACLs, firewall rules,
etc, as appropriate.
To test connectivity from another machine, try:
telnet <mail-server-ip> 25
telnet <mail-server-ip> 443
...to test basic SMTP and IMAP connectivity respectively. If SMTP
doesn't connect then you won't be able to receive mail.
Sending to <your-username>@<mail-server-ip> from a mail client on
another PC should hopefully result in a delivery. If you browse through
"Maildir" within the user's home directory you should find a file
containing the message contents.
Hope this helps,
