Hi,
I run a bot that automatically sends a newsletter to the mailing list wikipedia-fr-wikimag (https://lists.wikimedia.org/mailman/listinfo/wikipedia-fr-wikimag) by converting a wiki page. The publication was paused since 2019 but was restarted last week. However, when the bot tried to send the e-mail, nothing happened.
The list exists specifically for that reason and my bot is the only one to post there. The last time it works was in December 2019 (https://lists.wikimedia.org/pipermail/wikipedia-fr-wikimag/2019-December/000294.html).
On the bot side, there was no visible error when the message was sent. But it did not reach the mailing list. I am an admin of the list, and I didn't receive a message saying that the message was rejected or required approval, so I am unable to debug the issue. Do you know what could block the message?
Additional information:
- Manually re-running the script to send the e-mail didn't help.
- If I configure the bot to send an e-mail to me instead of the mailing list, it works, although my mail provider puts "[SPAM]" in the title. My first guess is that Wikimedia list server could filter it for the same reason. It would make sense: my bot runs on a VPS with an IP in the range 51.83.0.0/16, which is globally blocked on Wikipedia because it's full of compromised servers. Could it be the reason?
- The script that sends the e-mail looks like this: https://fr.wikipedia.org/wiki/Utilisateur:Orlodrim/Wikimag (no change since the last successful message sent). Another hypothesis is that it's buggy somehow, so the messages may look more spammy than e-mails generated by a well-behaved clients. However, I don't know how I could check.
