Hi all, I've been failing to receive some automated emails from both yahoo and gmail. The error smtpd is printing out is:
Jun 27 17:40:02 elysion smtpd[17570]: smtp-in: Failed command on session 00002741922c17e6: "MAIL FROM:<reg.mfsg22logixg2zlnmjsxeltomuys46lbnbxw6ltdn5ws2mjtg4zdgnjuhayta-hugo=osvaldobarrera.com...@returns.bulk.yahoo.com>" => 553 Sender address syntax error I'm wondering what the syntax error is. I tried looking at the RFCs a bit, but I've not found anything (though I'm sure that I skipped some important part). Is the "=" an invalid character, or does the address size exceed the limit? As an informtive note, I've noticed that these same automated emails (google groups invites, and yahoo password recoveries) fail to reach their recipients if the recipients are using hotmail.com/outlook.com, amongst other popular email providers some friends use, so I don't strictly think smtpd is doing something wrong - I'm just curious as to what's wrong with those addresses. Please note that I'm not complaining about this issue; I'm just asking what's wrong with this address and what RFC I should read (so yes, it *is* slighlty OT). Thanks, -- Hugo Osvaldo Barrera
