Steffen Kaiser:
I would give the http://wiki2.dovecot.org/PostLoginScripting a try.
I never used PostLoginScripting before. I have concerns about
additional serverload
if that scripting is executed for every pop3 login and every user. (
and there are *many* )
Maybe you can enable it for your dummy account via ExtraFields specifically.
That sounds I like additional scripting could be selective enabled via
ExtraFields?
It' try to find documentation ...
Because I wonder, if you will be successful with "throw a login
error with customised answer" [any MUA displays what it wants], you
might prefer a MUA-independ script or program that queries your
server. And if you are at it, maybe a dummy server with a self-made
script that returns "+OK POP3 your IP is ....", then return +FAIL
for any further command. You need to return the greeting and keep
the connection open, in order to bypass IDS firewalls.
I also thought about that.
Thanks for your constructive statement.
Andreas
