#
# Shorewall version 5 - SMTP Macro
#
# /usr/share/shorewall/macro.SMTP
#
#	This macro handles plaintext SMTP (email) traffic.  For SMTP
#	encrypted over SSL, use macro.SMTPS.  Note that STARTTLS can be
#	used over the standard STMP port, so the use of this macro
#	doesn't necessarily imply the use of an insecure connection.
#
#	Note: This macro handles traffic between an MUA (Email client)
#	and an MTA (mail server) or between MTAs. It does not enable
#	reading of email via POP3 or IMAP. For those you need to use
#	the POP3 or IMAP macros.
