I am using Postfix as an MTA but I see nowadays lot of spam going out of my
system. I have used transport based throttling for a domain but I am looking
for options for per sender based rate limiting. Can I achieve per user based
throttling using postfix or I have to use some 3rd party software ?
Throttling is not the solution to fight spam originating within your
network. If you know who is doing it, boot him. If you don't, identify who
it is, then boot him. Period. Why are you playing paddy cakes with a
spammer on your network?
If this spam is due to php/sql injection, fix/patch or eliminate the hole
that is being exploited instead of trying to throttle it.
Stan,
I've seen everything set up per the documents and all the online tests
showing that i'm not an open relay. I have no need for external
sendmail and I've used all the proper configs and all the suggestions
on the list, and I still get some guy with watches for sale who can
send mail anyway. When I asked on the list, I was told post my logs
etc, which would be very handy for a spammer probably reading this
list.
The spammer is already using your machine; showing us your
logs and config can't make it worse.
Without proper evidence of the problem we can't help you further.
