Emails sending from PA are not working

L3 Networker

Currently we are facing an issue with Emails which are not sent from palo alto firewall.

We have created a setting to send mail with reports but we are getting below error listed.


Connection to 465 failed. Failure when receiving data from the peer


Please share any document related to this error and a recommendation for this.

Generally speaking this simply means that your traffic is failing to send properly. Have you looking through your traffic logs or performed a packet capture to actually see if your allowing the traffic and your actually getting return traffic from Google? 

Can you share any related document for this to check.





We have Gsuite with which palo alto need to communicate and the mail needs to recepient mail id.

I have checked with service route and changed the service route to internet line from management line for tshoot purpose.

I have tried both 25 and 465 in 10.0.1 panos yet no luck.

In traffic log 465 traffic are getting as incomplete yet the action was allow.

I have configured under device---> service profile --->email with with port as 465 with no certificate profile---- Is it mandatory to provide a certificate profile?

I have given both username and password.


Please confirm me whether i need to configure the 15th  and 16th step from this document--- to get mail on my mailbox

G-Suite accounts are different and I don't think actually works these accounts. I believe that to set this up with a G-Suite account you'll want to go through and configure smtp relay services and use the 

Personally I would highly recommend setting up a relay and something like PostFix internally to relay those messages locally through to Gmail. 

As for your question regarding step 15 and 16, without setting up one or the either you'll never get any emails from your firewall. It's a good idea to configure both to meet best practices, but you could also just use this email profile for scheduled reports, so again whether or not you configure those steps is up to you.
