qmail not sending mails out

[wverboom]

Hi there,

My CentOS 7.0 server with Plesk 12 was working fine with Qmail.
Sinds a few days Qmail is not able to send out any mails.
In webmail it's trying and trying untill it times out.

We have changed it back to postfix and now it works fine again...but why is Qmail broke?
Also on a new install on CentOS 7 it's not working.

Any related error messages from Plesk maillog?

Nothing to see in the maillog! It just times out in the webmail.
The wheel keeps spinning for some time on the lower right.

It just times out in the webmail.

Ok. In this case any error messages in webmail log file?

Can you tell me where to find the log file for Roundcube?

Thanks.

I think the following errors are not related to the problem i have but they generate a lot of messages in the error log.
