Hello everybody
I had a perfectly working Postfix configuration, but after a server restart
something went weird. Postfix claims several users are unknown. It turns out
that these are aliases from my virtual_alias_maps file. I have the following in
main.cf:
virtual_alias_maps =

Just a wild guess... Is your Postfix chroot'ed, and if so, have the listed

Hello,
I've stumbled across one of our older systems and noticed a minor
problem in its mail delivery system.

Hello,
I run a Drupal 7 website on a CentOS 6.4 server
with postfix-2.6.6-2.2.el6_1.x86_64.
In the last few months the amount of fake users trying to register at my
website has increased dramatically - I get 2 or 3 of such registrations per
minute.
Mostly they have fake mail adresses with many

perhaps try
restriction classes in combination with regex sender
Thanks, I agree with all general advices...
But for now I just want to stop the flood

I don't want to add CAPTCHA to my

there haven't been a month without a challenge,

my last post in this thread because we are going off-topic
discard messages on a MTA is the *last resort* if nothing
else happens but not the solution for a broken web-app

A CAPTCHA isn't going to solve your problem either, my forums have
always had a rather hard-to-solve CAPTCHA enabled, and I too get
hundreds of these registrations per day with many dots @gmail.com
That said, I agree it'd be better to stop registrations from this format
in the first place, but

Yes, ok - it's my fault.
Next time I will ask a Postfix question here,
I shouldn't forget to add a disclaimer
