Good day!
I am setting up an email list for my local community (just myself right now). Being a nerd, I am using Amazon SES to send and receive emails. I have mailman installed on ec2 (using "pip install mailman") and it is working well enough to send an email to the list with
/opt/mailman/venv/bin/mailman inject -f <somefile>all@mymaillist.org
SES is putting incoming mail into an S3 bucket, one file per email. Using a small python program, I use the above command to send them to the list.
When I add a user (like myself) I get a welcome email from all-request@mymaillist.org. When I respond, the mail arrives in the S3 bucket, but I do not know how to give it to mailman3. The "inject" command will not work because there is no "all-request" mailing list.
How do I feed these administrative mails to mailman3?
Thank you.
I have tried netcat the email to the ?LMTP? port, but it fails:
(venv) [ec2-user@ip-10-0-3-253 mailman]$ nc localhost 8024 < /tmp/pbTw1oqmV1rZtHXV707Jcov264hr 220 ip-10-0-3-253.ec2.internal GNU Mailman LMTP runner 2.0 500 Error: command "RECEIVED-SPF:" not recognized 500 Error: command "AUTHENTICATION-RESULTS:" not recognized 500 Error: command "" not recognized 500 Error: command "" not recognized 502 5.5.1 Too many unrecognized commands, goodbye.
here is what the first few lines of an email file look like. (Some values have been changed)
