Mail only sent/received after clicking on 'retry' in the exim mail queue

[SvBoxel]

After working for several years with DA and CentOS i encountered a rather strange problem today.

All mails sent from users on my server are stuck in the mail queue, but after clicking on 'retry' in the exim mail queue they eventually are send. The same problem occurs with incoming messages. First they end up in the queue, and after clicking retry they end up in the right mailbox.

The exim maillog doesn't give that much details about the problem:

2015-04-18 16:42:43 1YjTxD-0002SF-Hl <= [email protected] H=52d9a988.cm-11-1c.dynamic.ziggo.nl (xxxx-MacBook-Pro.local) [xx.xxx.xxx.xxx] P=esmtpa A=login:[email protected] S=4450 [email protected] T="Test" from <[email protected]> for [xxxxx]@gmail.com

Which just looks normal.

I already tried to reset exim.conf back to its defaults and also did a complete flush of the spool and queue, but that didn't help.
Anyone had this before or has any suggestions on how to fix it?

Thanks!

Hello,

What is your server load? What are the values of

deliver_queue_load_max =
queue_only_load =

in your exim.conf?

Run

exigrep <Message-ID> /var/log/exim/mainlog

to get more details on a delayed email.

The exigreq command prints the following:

The server load is really low all the time and sure below 5.

Running the exigrep command prints the following:
