Simple local catch-all mail server
You don’t need “real” mail delivery on your machine?
But you want to receive e.g. status mails from cron?
You want to get all mails originating from localhost, regardless of the recipient, so you can detect services and programs gone rogue?
Try OpenSMTPD. There’s a package for Arch Linux, here’s the manual and here’s my config (/etc/smtpd/smtpd.conf):
# To accept external mail, replace with: listen on all listen on localhost # map any recipient to my user account table catchall { "@"="johnlate" } # "listen on localhost" should already take care of this reject from ! local # apply catchall mapping accept for any virtual <catchall> deliver to mbox # default rule, if I ever change the catch all mapping reject for any |
