Hi guys. I've got a strange delivery issue on my Linode using Debian, courier, and postfix. I have set all of this up with ISPConfig.

For some reason, after a couple of days, delivery just stops. I don't know why, as /var/log/mail.err, /var/log/mail.info, /var/log/mail.warn, and /var/log/mail.log don't tell me anything useful. The logs look like everything is working properly, yet no e-mail is delivered.

I've tried sending to the account I'm sending from to no avail, so getting mail from an outside source is even more of a stretch. The only fix I have is restarting the server, which is not something I want to do twice a week.

Any ideas would be appreciated.

Thanks

What exactly isn't going through? Mail from the outside to local recipients? Mail from the inside to outside recipients? Mail from the inside to local recipients? All three?

Does restarting Postfix cause the missing mail to be delivered?

Mail from the outside to local recipients and mail from the inside to local recipients. I can send outside recipients fine. (i.e., from the linode to a gmail account.) Nothing is showing up in the "Inbox" on the linode, if that makes things clearer.

I have not tried restarting postfix... I'll give that shot next time.

Thanks for the response!

That's why we're here! Run postconf and see what your values of local_recipient_maps, mail_spool_directory, and home_mailbox are.
