How can I setup Canon MF5550 on Linux box?

Linux mail setup, spam and online / offline server question?

• Best mail setup question ... Scenario: - Have own domain name, lets call it abc.com for example. - Host 1: Have linux server at home on a xDSL connection running sendmail, which is not always connected to the net. Running fetchmail off this box to Host 2 to get mail for abc.com out of user1 pop account. /etc/aliases file used to hold many aliases for abc.com - Host 2: Linux server (linode) permantly connected to the net running qmail + spamassassin, and with a rule of *@abc.com to be dumped into a pop mail account user1. Primary MX for abc.com points to Host 2. Secondary & Tertiary MX's for abc.com point to a backup spool where domain is hosted. Problem: - As Host 2 has a all to one mail mapping for abc.com, all mail for any email address is accepted. - Spamassassin helps filter spam on Host 2, - Aliases file is on host 1 (so aliases can be added/deleted easily) Is there an easier way to setup mail ... can a backup mail spool with no timeout on host 2 be setup just for abc.com

• Answer:

  I'm not familiar with qmail specifically, but assuming it has similar capabilities to most other MTAs, you can most likely configure host 2 to manually route mail (i.e., not via MX records) to host 1 as an "expensive mailer" (or whatever alternative terminology qmail might use to always defer delivery). Whenever host 1 connects to the network, connect to host 2 qmail and issue an ETRN SMTP command with your client name to process the queued messages. This will initiate a new SMTP connection to host 1.
