They don't reject with 5xx because they're not rejecting that message, they are rate-limiting you or the network you're on. I get this often, because one user forwards their mail to gmail, including all the spam. Google rejects the spam, and from time to time also rate-limits me. Which I don't care about, because I send very little mail, and it goes through on the next run. Google is brain-dead about "unsolicited" mail - whatever machine learning it's doing, is crap. Their latest daftness (latest in my noticing it, anyway) is rate-limiting on the basis of too many recipients for a single message-id, where "too many" varies from 6 to 30. You'd think they'd never heard of organization mailing lists. Julian. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
