Not everyone is fighter pilot or race car driver material. Likewise not everyone is mailop material. If you've made multiple attempts to set this up and failed each time, I'd say it's pretty clear you simply lack the aptitude and prerequisite IP networking and DNS knowledge. How on earth will you even begin to troubleshoot when something breaks, when you have no understanding of how the various layers of the mail stack actually work, how SMTP works? When your mail stops arriving the first thing you will consider is that there a problem with Postfix or Dovecot, that -you- did something wrong. You'll blame yourself because you know you are the weak link. So you'll start monkeying with your Postfix configuration and break it, even though its working correctly. In reality, 99% of the time mail flow problems are due to a routing problem within your broadband provider's network, a down or flapping link between your provider and one of its peers or somewhere else on the net, a DNS lookup issue possibly caused by the former network issues, etc, etc. Running an MX MTA/mailbox server is 90% networking, 10% MTA/mailbox management, especially for a family mail server with 2 mailboxes connected via less than reliable broadband, no SLA, etc. The first tools that get pulled out for diagnosing an MX problem are dig, traceroute, ping, telnet, etc. NOT 'postfix reload'. Not 'vi /etc/postfix/main.cf' or 'vi /etc/postfix/master.cf'. If you don't have sufficient experience with such network diagnostic tools, don't know how to use them, why you're using them, or when to use which one, you don't have any business running an MX MTA. Attempting to do so will simply cause you problems and burn huge amounts of your time, and will completely overshadow any benefits you might receive from having your mailboxes in a server on the premises. Setting up Postfix and Dovecot should take no more than a couple of hours each, most of it reading docs. Creating your MX and SPF records takes a few minutes, though it may be many hours before they go live depending on your SOA TTL. Programming an inbound TCP 25 PAT mapping on your router should take only a few minutes. None of this is particularly difficult. Figuring out what ports your provider does/not block may be more difficult, as well as getting those blocks removed. If you have a static IP, and especially if you pay extra for it, this shouldn't be a problem. I am not indicting your aptitude nor abilities. I am simply giving you a healthy dose of reality so your eyes are wide open going forward. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
