Re: Two domains names under the same IP: how to handle this issue ?

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.

Re: Spam notification

[Reko Turja]

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.

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.

Re: Looking for opinions on FreeBSD OS for Postfix

[Reko Turja]

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.
