Backlog of email to Xtra

We currently have a growing queue of email to xtra.co.nz on all of our mail servers. According to Xtra's website, there are no issues. Is this just our problem or is this a little more of a generic problem ? We are just getting lost of "421 Message rejected (in reply to end of DATA command)" errors. Glen.

Key indicators aren't showing any issues with the platform so are you able to capture some timestamped telnet logs and email them through to me? -- Regards, Ted Grenfell Technology Operations Manager IS Online Services T +64 9 359 5854 (extn 93254) F +64 9 377 0781 M +64 27 443 5455 E ted.grenfell(a)telecom.co.nz W www.telecom.co.nz Level 11, Telecom House, 8 Hereford Street, Private Bag 92028, Auckland CBD, New Zealand ________________________________ "This communication, including any attachments, is confidential.

I am seeing the same for a large number of email to Xtra (not all) (I've emailed Ted some logs) for it Thanks

Having now looked more closely at a number of the messages in the queue, it would appear that they would probably all be classified as spam. So it would seem that the filters on mta.xtra.co.nz are rejecting messages with a 421 rather than a 5xx error, hence our growing queues. Is this a change in policy ? Reject with a temporary failure something which is never going to be delivered is simply deferring load as the mail will be represented until our servers giveup (currently a number of days).

That's not Xtra's MX: $ host -t mx xtra.co.nz xtra.co.nz mail is handled by 10 mta.xtra.co.nz. $ host mta.xtra.co.nz mta.xtra.co.nz has address 210.54.141.1 You sent e-mails to: $ host smtp.xtra.co.nz smtp.xtra.co.nz has address 210.54.141.2 (which might be the same cluster of servers but still ...). That being said - I don't see any problems with e-mails going to Xtra either (our network sent about 10k today, average delivery time was only 3ms). Cheers, Bojan
