Ispcp cannot receive emails

[kilburn]

"Relay access denied" in this case means that postfix thinks that the destination domain of the e-mail is *not* handled by this server. In the low level, this means that the domain is not found in the virtual domains table (/etc/postfix/ispcp/domains).

However, it is really strange that the domain is not there if you added it through the panel and did not set its mail limit to 0. You can either:

(1) manually add the domain there (and to /etc/ispcp/postfix/working/domains), and then run "postmap /etc/postfix/ispcp/domains" to rebuild the table. This should fix emails for that domain, but no the root cause.

(2) remove and readd the domain, to check if it is now added properly. If it is not, you can file a bug and we'll try to get into the details of what is going wrong there to fix it.
