Hello,

	My MX servers receive a lot of spam that come from an open relay (a 
regular SMTP that I cannot blacklist). I don't find any solution to 
accept all mails that come from SMTP domain and blacklist all mails that 
come from this SMTP with another domain in mail address.

SMTP: domain1.fr

	Accept : all mails like *@...
	Reject : all mails that don't match *@... and that come from 
smtp.domain1.fr.

	I have tried to use from and rcpt, but I don't know how specify SMTP 
adresse...

	Any idea ?

	Regards,

	JKB
