Re: [fetchmail]Fetchmail and postfix

2005-08-28 14:32:39


Thanks for the info, unfortunately the object was to reduce the amount of
processing required for each email.  

It would seem that this would make the process more convoluted and add to
the processing required.



I guess the botom line is that there's no simple answer.  I was
hoping that there was one but my searching hadn't found one and after this
little exchange it seems that there isn't one.



Oh well it was just a thought.  





Thx none the less

 BTW I noticed in the FAQ that there are hints on setting
fetchmail up

with

several different MDAs, but nothing for postfix.  Are there
any handy

dandy

hints on using this combination?



Well, postfix is an MTA (though it may also contain an MDA, I
don't

know enough about postfix).



It has three MDAs, local(8) and virtual(8), and finally pipe(8)
which

relays to yet another shell command (usually maildrop or something
like

that).



In short, no.  Fetchmail can't fake the IP the mail is coming
from.

I'm afraid you'll need to find some other way of filtering than
by the

source IP.



It is however possible to configure more than one Postfix smtpd
server,

so fetchmail could inject into a different SMTP port, where the

"permit_mynetworks" wouldn't apply.



Shuffling around smtpd_*_restrictions in Postfix's main.cf may also

help, to put reject lists before permit_mynetworks - it usually does
no

harm unless someone in the local network is trying to send mail with
a

banned domain in the envelope sender.
