SMTP weird characters

L1 Bithead

Hi everyone!

My client's SMTP traffic goes through ASA and Palo Alto and some other network application devices such as proxies and stuff.

At some point, the SMTP message gets some SMTP characters added.

 

I removed ASA ESMTP inspection just in case, and still the characters appear.

Is there any kind of inspection such as the one in ASA to disable in Palo Alto, just to check whether the FW is messing up with the emails or not?

 

Thank you!

Regards

Just for testing you can create a policy to allow smtp applicaiton for a particular source and destination don't apply security profiles and check if you are stilll getting that character or not.
