Hi,
I hope that someone can help me. Last night I had a strange
problem. Every email that came in was there twice. Emails that
I would normally get 2 copies of, I received 4 copies of. Any
ideas on what could cause this?
Careful examination of the logs will probably enlighten you.
With no information, speculation is pointless.
I have been looking at the logs.
I have never seen this before:
Oct 27 15:10:03 agnus postfix[27341]: dict_eval: expand
$myhostname, $mydomain, localhost.$mydomain ->
agnus.datazap.net, datazap.net, localhost.datazap.net
Oct 27 15:10:03 agnus postfix[27341]: dict_eval: expand
$mydestination -> agnus.datazap.net, datazap.net,
localhost.datazap.net
Oct 27 15:10:03 agnus postfix[27341]: dict_eval: expand
$relay_domains -> agnus.datazap.net, datazap.net,
localhost.datazap.net
Turn off verbose logging. That may help your CPU usage too.
Not likely. A broken alias is the first guess. What did you
change?
I didn't change anything and I can't find any duplicates in
the log. I have to wonder if the problem didn't occur after it
was delivered to procmail.
A procmail delivery problem wouldn't surprise me.
I then have postfix pass the email to procmail where it is
filtered with bogofilter. I keep giving bogofilter more spam
to look at, but it doesn't seem to block all the spam anymore,
although it blocks some spam. When I first installed it,
bogofilter worked very well.
Sounds as if bogofilter is poorly trained. Ask for help on a
bogofilter forum, or just delete the database and start over.
I have deleted the database many times and started over. If I
delete the older spam and the spam that is out of order being
sorted by date it will work again for a while.
If bogofilter isn't working for you, try another tool. But
remember that nothing will work long term without some attention.
problems lately have been with email. I feel like I need to
get postfix to stop using so much cpu.
Show some evidence. Postfix shouldn't use very much CPU.
each mail server sending 100's of emails. When I used to use
postgray (I gave that up years ago), postgray would use all
the cpu.
So you have a 200MHz 386 or something?
The problem is these same emails continue to be bounced by my
mail server. If I just let them be delivered then it does
Sounds as if you've foolishly set "soft_bounce = yes"
This would be a good time to share your "postconf -n" output
and the contents of master.cf
lower the amount of mail attempted to be sent to it by like
90%. I would have never though of this idea, but I read an
ariticle online on how to stop fighting the battle on spam and
winning the war. This is one of the things they recommend.
This is bad advice. Not everything you read on the internet
is helpful.
Very bad idea. Reject mail you don't intend to deliver.
I thought that someone would say that and really I am not sure
how to deal with the over flow of spam. Although, I can see
how just letting it go through and not fighting it only to
have a filter look at it later may work.
Nothing is more efficient than rejecting the mail before it's
accepted. Period.
I would really like to filter email after the mail server
passes it to procmail, because I have noticed email that is
forwarded from another mail server the filtering in Postfix
doesn't seem to do anything for it, it may just as well
immediately give it to procmail for filtering. Also, I have
considered using something like fetchmail to get the mail from
other mail servers and then passing it through procmail for
filtering. The forwarded emails seem to be one of the reasons
So get rid of the forwarded accounts.
