Hi,
The mails sent by weblate originate from an IP address block that was unfortunately blocked.
Aug 28 19:55:19 weblate postfix/smtp[31747]: DF82B4A74A: to=, relay=spool.mail.gandi.net[217.70.184.6]:25, delay=0.39, delays=0.01/0.02/0.35/0.02, dsn=5.7.1, status=bounced (host spool.mail.gandi.net[217.70.184.6] said: 554 5.7.1 Service unavailable; Client host [145.239.12.117] blocked using pbl.spamhaus.org; https://www.spamhaus.org/query/ip/145.239.12.117 (in reply to RCPT TO command))
I went ahead and asked for removal. Got confirmations right now that this is in progress. It will take 30 minutes to complete but I don’t know how long it will take for gandi or other mail servers to update.
Cheers
