sophisticated spam filtering

[Bertold Kolics <bertold@sztaki.hu>]

Hi All,

I wonder whether one can

- enable incoming mail from a given MAIL FROM address even if the sender's
domain is blocked (in any way)

- custumize messages sent by zmailer in case of mail blocking 

Thanks for your help.

Furthermore, I noticed that zmailer-2.99.50s8 (running on Solaris
2.6) often closes connection without sending out the error message.
Example:
1. a config line from smtp-policy:

tohotom.vein.hu                 = _bulk_mail

2. I log into tohotom.vein.hu and try to establish an SMTP session:

tohotom:~$ telnet lutra.sztaki.hu smtp
Trying 193.225.86.1...
Connected to lutra.sztaki.hu.
Escape character is '^]'.
220 lutra.sztaki.hu ZMailer Server 2.99.50-s8 #2 ESMTP+IDENT ready at Wed,

HELO tohotom.vein.hu
250 lutra.sztaki.hu Hello tohotom.vein.hu
MAIL FROM: <bertold@tohotom.vein.hu>
Connection closed by foreign host.
tohotom:~$ 

In smtpserver I see:
12174#  connection from tohotom.vein.hu ipcnt 1 ident: bertold

12174w  453-4.7.1 Policy analysis reported:

Is this normal?

With regards,
