Hi! We're running the postfix-users ML on list.sys4.de, and all over a sudden we're being tempfailed by GMAIL:
421-4.7.28 Gmail has detected an unusual rate of unsolicited mail. To protect 421-4.7.28 our users from spam, mail has been temporarily rate limited. Please 421-4.7.28 visit 421-4.7.28 https://support.google.com/mail/?p=UnsolicitedRateLimitError to 421 4.7.28 review our Bulk Email Senders Guidelines. s8-20020adfea88000000b0032fba209e8esi6123538wrm.543 - gsmtp (in reply to end of DATA command) SPF, DKIM, DMARC, douoble-opt-in, valid forward and reverse DNS records are all in place, and it's been working ok for quite some time -- so it's a bit unclear what has changed here or what caused the block... And since it's the postfix-users mailinglist, we're dead sure it's not spam we're sending! -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 [email protected] https://www.charite.de _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
