Running postfix-2.2.10-1.2.1.el4_7.centos:
When I try to send eMail to a person who uses Yahoo! as their eMail
provider, but to a non-Yahoo domain, I get:
Feb 1 16:34:59 mail postfix/smtp[10551]: 8CE431140DB: host
mx1.biz.mail.yahoo.com[68.142.202.129] said: 451 Resources temporarily
not available - Please try again later [#4.16.5]. (in reply to end of
DATA command)
Feb 1 16:35:00 mail postfix/smtp[10551]: 8CE431140DB:
to=<[email protected]>, relay=mx1.biz.mail.yahoo.com[74.6.140.31],
delay=2, status=sent (250 ok dirdel)
At first blush this looks like a 451 temporary bounce, but the next line
seems to imply that the message was delivered. However, the user never
receives my messages when sent from my server, and "mailq" shows my
queue as empty. When I send from a gMail account (obviously using
Google's servers), he receives them.
Has anyone else encountered this? Is Yahoo! adhering to standards?
