Hi,
I keep on having tons of mails in my Exim Queue, and most of them is SPAM
like this one:
************************************
Server# exim -q -v
************************************
LOG: queue_run MAIN

250 HELP
SMTP>> MAIL FROM:<> SIZE=4292
************************************
Notice the Mail From command = <>
************************************
My question is, how can I block <> senders and recipients with Exim, or do I
need a Spam filter?
Also, how are Spammers able to relay through my server? Since I only allow
relaying for certain IP's and domains. Or are they intelligent enough to
relay mails using the same host name (server name)?
Hope someone could be of assistance.
Regards
Schalk
