SYNOPSIS

aiosmtpd [options]

Description

This program provides an RFC 5321 compliant SMTP server that supports customizable extensions.

OPTIONS

-h, --help Show this help message and exit
-v, --version Show program’s version number and exit.
-n, --nosetuid 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).
-c CLASSPATH, --class CLASSPATH
 

Use the given class (as a Python dotted import path) as the handler class for SMTP events. This class can process received messages and do other actions during the SMTP dialog. If not give, this uses a debugging handler by default.

When given all remaining positional arguments are passed as arguments to the class’s @classmethod from_cli() method, which should do any appropriate type conversion, and then return an instance of the handler class.

-s SIZE, --size SIZE
 Restrict the total size of the incoming message to SIZE number of bytes via the RFC 1870 SIZE extension. Defaults to 33554432 bytes.
-u, --smtputf8 Enable the SMTPUTF8 extension and behave as an RFC 6531 SMTP proxy.
-d, --debug Increase debugging output.
-l [HOST:PORT], –listen [HOST:PORT]
Optional host and port to listen on. If the PORT part is not given, then port 8025 is used. If only :PORT is given, then localhost is used for the hostname. If neither are given, localhost:8025 is used.
