No it is not just one host it is many. I have tried to confirm the users claim, and although he is a reliable source, I wasn't able to replicate the issue.
The recipient did not get the email anyway, as far as I know. There was no response, and in this case it was a customer service request. I have contacted Postmasters about this issue, not many have responded. The most interesting response I got was one asking if we made a connection, did something (which would cause a delay) and then tried to send the email. It seems to me any preprocessing of email is done before the connection is opened. James On Jul 1, 2010, at 6:42 PM, Noel Jones wrote: On 7/1/2010 4:55 PM, James R.

Is it just this one host that's deferring your mail? Did the recipient get the mail anyway? Does the mail eventually get delivered? Have you confirmed the user's claim that only plain-text mail is deferred? Have you contacted the postmaster of 64.128.185.221? If you can deliver to other hosts OK, the problem is at 64.128.185.221. ---------- The Bounce ---------- Diagnostic information for administrators: Generating server: relay0.edhance.com<http://relay0.edhance.com> <http://relay0.edhance.com> sa...@2co.com<mailto:sa...@2co.com> <mailto:sa...@2co.com> #< #4.4.2 X-Postfix; lost connection with mail.2co.com[64.128.185.221] while sending end of data -- message may be sent more than once> #SMTP# This isn't a bounce notice; it's a "message delayed" notice.
