Emerges that take days have trained me to not to watch them happen. I read the latest elog of all packages once a month, some send me mail; but if Postfix shut down before delivery, I would not get it at all. I use elogviewer once a month, so I'll probably see it in a couple of weeks. It's nice to know what happened. Not much mail actually goes through this system, so while this has been something of a puzzle, no major harm was done. It's nice to have the explanation. Thanks. ++ kevin -- Kevin O'Gorman, PhD

If so, the recent Perl 5.12 update killed my Postfix+SPF setup. In the main.info log; warning: command /usr/bin/perl exit status 2. Haven't had time to look at it yet.

You're one step ahead of me in that I haven't even configured postfix once, but any MTAs that I have configured would generate copious logs with errors when things borked. If you don't want to share these and the error is not obvious, then try replicating the postfix steps using telnet, or nc, or openssl s_client to see what the ISP's server returns. Some ISPs change ports (e.g. disable port 25) to minimised spam sent by botnets, so that's the first thing I would check. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Start configuring Postfix again from scratch, following the guide (E.G. http://en.gentoo-wiki.com/wiki/Postfix). For a basic install of Postfix - i.e. outgoing proxy, on your LAN, behind a router - then there's very little you need to configure. About 3 or 4 lines in main.cf. You should be doing stuff like telnetting to port 25 http://www.yuki-onna.co.uk/email/smtp.html and `sendmail kevin file.txt` (assuming kevin is a valid local user and you know how to read the mailbox). If there's no reply on port 25 then you know postfix isn't starting. Seriously, the first place to look is ALWAYS the logs. Once you've got mail working, consider something like: $ grep ELOG /etc/make.conf PORTAGE_ELOG_CLASSES=warn error log PORTAGE_ELOG_SYSTEM=save mail PORTAGE_ELOG_MAILURI=root PORTAGE_ELOG_MAILFROM=port...@yourhostname $ Note that postmaster root should be configured in /etc/mail/aliases - typically postmaster - root, root - you. About the hardest part of setting up a Postfix install is running the newaliases command. Stroller.

About the hardest part of setting up a Postfix install is running the newaliases command. The only hard part for me was that I needed to set up sasl since the site I relay through (smtp.cs.nyu.edu) requires authentication. If you don't need this authentication with password, then there is really nothing hard. A few revisions ago postfix changed this but supplied a legacy version that I use. Lately, the updates have been painless (although stressful, due to the importance of mail). As mentioned the logs are helpful and the verbosity can be configured. From my current main.cf # DEBUGGING CONTROL # # The debug_peer_level parameter specifies the increment in verbose # logging level when an SMTP client or server host name or address # matches a pattern in the debug_peer_list parameter. # debug_peer_level = 2 # The debug_peer_list parameter specifies an optional list of domain # or network patterns, /file/name patterns or type:name tables. When # an SMTP client or server host name or address matches a pattern, # increase the verbose logging level by the amount specified in the # debug_peer_level parameter. # #debug_peer_list = 127.0.0.1 #debug_peer_list = some.domain #ajg: uncomment next line when debugging authentication #debug_peer_list = smtp.cs.nyu.edu Good luck, allan

If you just relay your mail to your ISP, then you may be able to simplify your life using something like nbsmtp. I used to take mail locally, via sendmail, since I stopped using uucp around 1987. When I found out about postfix, it was good riddance to those re-write rules. Then I simplified by sending it all to the ISP so I now have just 3 mail spools: 1) gmail for all my mailing lists because they'll let me spool forever it seems -- my quota is over 7GB and I'm using maybe 30% after about 8 years. This is stuff were privacy doesn't matter to me. 2) My ISP, because it's more reliable than I can do at home. 3) Work, which I can't avoid. At home I stuck to Postfix because until now it never gave me a lick of trouble. I'm pretty old and no longer get much joy out of learning yet another tool for its own sake. It's gotta be LOTS better than what I have. In the last year I've only taken on m4, Fireworks and Dreamweaver. There are good enough reasons for each. If I were a few decades younger, this would have been good advice, so thanks for the tip. -- Kevin O'Gorman, PhD
