undelivered mail return

[ephigenie]

you should remove the corresponding domain from the /etc/postfix/ispcp/domains file and run
postmap /etc/postfix/ispcp/domains . Replace this file as well /etc/ispcp/postfix/working/domains with the one edited before.

Try sending the mail again - it should work. Problem : if you change something in the mail config of that domain it will be set again in the file ... i'll integrate that into the 1.1 as a new feature (deactivate mail completely for a domain) because i wrote already a patch for a customer for exactly this functionality.
