Messages being forward to SC account failing


Recommended Posts

Gretings one and all...

I'm hoping for some assistance identifying the place to resolve a problem I'm having with mail reaching my SpamCop account.

On a fairly regular basis but not everytime senders get the following error when sending a message addressed to me at xxx[at]cnet.org.

yyyyy[at]spamcop.net (generated from xxx[at]cnet.org)
SMTP error from remote mail server after RCPT
host smtp-gw.x-mailer.co.uk []: 550-Callout verification failed:
553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) 

The route the mail follows is that anything addressed to xxx[at]cnet.org passes first through a spam filter at the ISP.

If the message passes the filter test it goes to xxx[at]cnet.org which forwards directly to yyyyy[at]spamcop.net

My sense is that the transaction is failing at the initial spam filter but could it be that the SpamCop server is saying 'no thanks I don't want that message.'

The headers for a sample item of mail returned to a sender follows below.

Any inspired suggestions gratefully received.

This is similar to the error message seen in another thread here. http://forum.spamcop.net/forums/index.php?showtopic=4990 Please read that thread if you have not already.

In that case, it seems his email account was closed. Have you attempted to send test messages directly to your spamcop email account?

Because of the similar messages, however, perhaps there is some issue with spamcop right now. Not sure exactly what that might be yet, though.

Not saying that "the" answer is here ... and I sure have no knowledge of configurations involved ... what I am going with is that this linked item includes some discussion with documentation provided from Exim ... I'm keying on the described "sometimes" part of the issue. What timing issues may be involved, whether the "fix" might be as simple as espoused n the linked article, hard to say from here.

What would be needed is one or two more of these failed items, header data such that date/time can be established, sent off to JT for his log analysis to see what's happening from that perspecitive. (doubting that the other parties involved would share log data with you, though you could ask ..??)

Note PMed re non-arrival of test.

Meanwhile I've changed my routing so that for now I'm collecting mail into the SpamCop account using a POP3 collection to see if  that fixes the issue.


No bounce yet to help fill in the blanks ... logged in directly to also check the other possible folders, but ....
