Title: sending email slow to one particular domain
Post by: scree74 on September 19, 2013, 05:27:17 PM
Good afternoon

I am having an issue with sending email to a specific domain
it showing the following line in the Mail Host Analysis

sbytes      mess  tries      xdelay         host
13487510 37     1157     22825.82     Someones-domain.co.uk (this is the not the real domain)

How can I trouble shoot where the problem is any assistance would be much appreciated.

Thank you in advance
Scott

Have a look at the log files:

/var/log/qpsmtp/current
/var/log/qmail/current

Have a look at the log files:

/var/log/qpsmtp/current
/var/log/qmail/current

Also look at the maillog analysis option in the server-manager.

You would probably get quicker diagnosis of the problem if you just named the domain. The problem is likely to be with their DNS or mail server setup.

If you have not pinged the site and if the site will return a ping.
I would try pinging the site.
I have seen too much internet supplier issues lately myself.

Is the problem that the domain looks funny in the qmail log report, or is the problem that you have users at Someones-domain.co.uk complaining that email doesn't arrive for hours after you send it?

If the problem is the number reported in the log, this is likely a log-related issue.  Perhaps their mailserver uses greylisting, and refuses all email until re-submitted.  Perhaps their mailserver returns a soft decline for all non-existing mailboxes, and your server keeps trying to deliver messages to departed users at Someones-domain.co.uk for a couple days, skewing the reported numbers.

If the problem is with delivering email to a specific user at Someones-domain.co.uk, get them to send you back one of the delayed emails *as an attachment* so you can look at the headers in the message to see where the delay was introduced.
