Hello, I've setup PRTG installation and I got problem with SMTP Delivery notification. Here the debug collected from the PRTG core server:

I have no idea about the reason it fails, please someone could give me a suggestion? The PRG release is PRTG Network Monitor 13.4.7.3747. Thanks

Hello,

thank you very much for your KB-Post. The basic SMTP-Connection works, that is shown by the successful EHLO-Command. But then sending the mail runs into a timeout. That could be caused by Tarpitting, or Blacklisting.
Please also try using a different email address to send the email notifications from PRTG.

best regards.

Hi!

Thanks for the solution. I was setting up a new PRTG server. I used the old prtg configuration.dat file and copied to the new server.

Everything was working fine. I had issues with the email notifications. As mentioned in this post, i changed the from email address and eveything is working fine now.

old from address : [email protected] new from address : [email protected]

Thank you.

Changing the "from" address as said by latiff fixed it for me too.
