aiospamc is a client for SpamAssassin that you can use as a library or command line tool.

The implementation is based on asyncio; so you can use it in your applications for asynchronous calls.

The command line interface provides user-friendly access to SpamAssassin server commands and provides both JSON and user-consumable outputs.

Detailed documentation can be found at: https://aiospamc.readthedocs.io/

• Python 3.8 or higher
• certifi for updated certificate authorities
• loguru for structured logging
• typer for the command line interface

aiospamc is your interface to SpamAssassin through CLI. To submit a message for a score, use:

# Take the output of gtube.msg and have SpamAssasin return a score
$ cat ./gtube.msg | aiospamc check
1000.0/5.0

# Ping the server
$ aiospamc ping
PONG

If your spam filter supports it, the GTUBE provides a test by which you
can verify that the filter is installed correctly and is detecting incoming
spam. You can send yourself a test mail containing the following string of
characters (in upper case and with no white spaces and line breaks):

XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X

You should send this test mail from an account outside of your network.
