Block email sent to domain as part of a recipient list [message #133412]

Hi All,

I am trying to figure out solutions to limit SPAM (either incoming or outgoing) in my organization and see if there is a feature that can do that in current Kerio connect version (9.2.0 (2213)

Most of the incoming SPAM sent to my organization includes one or more emails that belong to our domain as part of an email list (i.e. the spam email is sent To: xxxx_group).

My question: is there a feature in Kerio that I can configure to block incoming emails sent to certain (not all) email accounts as part of a mailing list?

Many thanks,
Ferro

Thanks,

I think the server rules solve your problem. For example drop all messages for specific recipient, if the sender is not from your/defined domains. To avoid fake senders from your own domain, use SPF.

Also do not allow sending of messages to mailing list for all, only for mailing-list members.

Server rules: http://kb.kerio.com/1831
SPF: http://kb.kerio.com/248 & http://kb.kerio.com/1173
