Emails to Plusnet Broken Pipe with attachments.
We have a lot of users trying to email plusnet customers but unable to do so. When the users send emails without attachments, it works fine, but with attachments they sit there in the queue and when we push them, we just see a broken pipe error. We have tried changing timeouts to higher values, but it seems what ever we make them, after 2 minutes we get a broken pipe error. This seems to have started since your customers migrated to Plusnet Cloudmark Gateway.
For example -
<email@example.com>... Connecting to mx.avasin.plus.net. via esmtp...
220 avasin06.plus.net Plusnet Cloudmark Gateway ESMTP server ready
>>> EHLO mydomain.com
250-avasin06.plus.net hello [my ip address], pleased to meet you
>>> MAIL From:<firstname.lastname@example.org> SIZE=589873
250 <email@example.com> sender ok
>>> RCPT To:<firstname.lastname@example.org>
250 <email@example.com> recipient ok
354 enter mail, end with "." on a line by itself
timeout writing message to mx.avasin.plus.net.: Broken pipe
Please contact me off list for full headers and I will supply them to you.
I have tried calling your phone number but I simply cannot sit there on hold for the duration it takes to speak to a human being.
Re: Emails to Plusnet Broken Pipe with attachments.
Drop me a PM containing the finer detail and I'll try and find some time to take a look. Won't be until next week at the earliest though.
