SMTP Server (CSESmtp)

This module implements SMTP protocol and is used to process incoming mail. SMTP Client receives incoming messages, applies certain spam filtering methods (DNSBL, RHSBL, SPF, RFC restrictions, Greylisting, Tarpiting, white/black lists) and backs up the incoming messages as *.qeml files to the incoming queue folder “%CSE%\mail\queue\inc” for further processing by other modules.
