Hi,
I use virtual domains to handle several domains for all the adresses on the
same account. But there's a problem with this configuration, because if a
spammer sends a mail to randomemail AT domain1 DOT com, postfix answers that the
user does not exist, without sending a mail (perfect), but if he sends it to
randomemail AT domain2 DOT com, postfix sends 250 OK, forwards it to
randomemail AT domain1 DOT com, and then an "undeliverable mail" is sent to the
spammer (and of course, its address doesn't exist...). This is the most
important part of the load of my mail server !!!
my main.cf :
virtual_maps = mysql:/etc/postfix/mysql-virtual.cf
Any idea ?
Don't use wildcard rewrites such as:
@domain1.tld @domain2.tld
Rather use specific entries for each domain.
