i want to configure a local / lan email server on linux, my sendmail is working fine but how do i download mails from a catch all account and distribute locally, as i dont hv a dedicated internet connection.
You would need to use a program like fetchmail to download the catchall mailbox. Check the man page for info on 'maildrop' ... that should get you going.
Sendmail is already preconfigured to work... I guess all you would need to so is configure the /etc/mail/local-host-names file or /etc/mail/sendmail.cw (if it still exists) to accept mail for you domain...
