Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]]
Options:
--nosetuid
-n
This program generally tries to setuid `nobody', unless this flag is
set. The setuid call will fail if this program is not run as root (in
which case, use this flag).
--version
-V
Print the version number and exit.
--class classname
-c classname
Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by
default.
--size limit
-s limit
Restrict the total size of the incoming message to "limit" number of
bytes via the RFC 1870 SIZE extension. Defaults to 33554432 bytes.
--smtputf8
-u
Enable the SMTPUTF8 extension and behave as an RFC 6531 smtp proxy.
--debug
-d
Turn on debugging prints.
--help
-h
Print this message and exit.
Version: %(__version__)s
If localhost is not given then `localhost' is used, and if localport is not
given then 8025 is used. If remotehost is not given then `localhost' is used,
and if remoteport is not given, then 25 is used.
