Re: Two domains names under the same IP: how to handle this issue ?
-Original Message- From: Miles Fidelman The original poster's question caught my attention - the RFCs suggest that there should be only one PTR record per IP address -- which begs the question of what do when one is serving multiple domains behind that You set up the other domains so that the DNS has the "main" name as MX and the server sends mail even for the other domains using the server real name. In addition, setting up things like SPF and DKIM records for all the domains and making the "main" MX the authorised sender for them helps with validation. -Reko
Re: Spam notification
I'm not a great fan of quarantining, although it works fairly well for webmail systems where the quarantine can be accessed through the same interface as the inbox (eg, Gmail and Hotmail). It's less helpful where mail is delivered to a POP3 or IMAP box as users have to go to a separate interface to check the quarantine. With quarantine and IMAP, one approach is using sieve with IMAP server and forwarding the border cases automatically via sieve rules to users junk/spam folder. That way quarantine can be accessed from the regular mail client or web interface and checked by the user him/herself if important mail seems to be missing. At least Cyrus can do this pretty painlessly, and I think Dovecot does support sieve these days too. -Reko
Re: building on FreeBSD 8.0?
-- From: Sent: Tuesday, December 01, 2009 12:40 AM To: Subject: building on FreeBSD 8.0? I know there are instructions in the INSTALL document how to "port" postfix to "unsupported systems" but I wonder if the list here has any help for getting postfix built on newly released FreeBSD 8.0. . . Uhh, good reason for not using the ports system? Been working a treat for me in 8.0 betas and RC's. -Reko
Re: Looking for opinions on FreeBSD OS for Postfix
I'm considering FreeBSD as an alternative, but I was wondering what people think of FreeBSD as a platform for Postfix. It's obviously not as easy to maintain as Ubuntu, but it does have a reputation for stability. Any thoughts, recommendations or experiences would be appreciated. As you still have plenty of time until the possible switchover, I definitely recommend FreeBSD 8, once out of the BETA and RC stage. The new NFS implementation alone would be worth it. My experience on FreeBSD is that if possible, maintenance is a breeze, if you dont mind digging bit more inside - the graphical tools might be lacking, but then the automation of updates and the port system are something that makes BSD's definitely an easy to administer system for me. For what it's worth I'm running postfix on all my BSD machines and it has never let me down. And of course man pages and the excellent handbook are your friends. -Reko
