[9.2.3] Suddenly no emails being sent or recieved...

[DaleH]

I am NOT a Plesk person (I'm a cPanel-er) in the slightest (it took me over a month to figure out how to set my DNS settings!!) however I have encountered a problem that I've been trying to fix for the past two weeks and it's really starting to stress me out heavily.

Up until two weeks ago my email was going fine, I could send and receive emails from the domain that I've assigned to my Plesk server (I usually use Mozilla Thunderbird), however now emails are not being sent with my gMail email account chucking me this Delivery Status Notification:

"Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 451 451 qq temporary problem (#4.3.0) (state 18)."

Also back an error too:

"There was an error sending your message: sendmail returned error code 111"

I've contacted my host about it and they cannot seem to find a fix to it, also many other people that have years of knowledge with Plesk have also said the same thing too. As my site relies on email stuff these past two weeks have lost me a couple of hundred pounds - so I'm obviously not very happy at all.

I'm not sure how it has happened as it was working one night, I went to sleep, woke up and it wasn't working.

Please explain any techniques in the simplest of terms please - as I said previously - I am NOT a Plesk person and cannot understand much when I've been trying to Google an answer.

Seems there are problems with selinux polices. Check if selinux is enabled in the system:

# getenforce
Enabled

Try to temporary disable it with the "setenforce 0" command and check that mailserver works fine. If it helps, try to reinstall 'psa-selinux' package, it should configure polices for Plesk.

I think I have a similar problem. One of my clients is having trouble receiving emails from one server escpecifically and I've found out that everytime a message from that server arrvives the following message is shown in the maillog:

I've already turned off the spam filter and the greylisting and it started happenning since I updated Plesk to 9.5.4 version.
I hope someone can help me because my client is loosing his patience.
