# Shorewall version 4 - 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.
