Comment:

 Hi there, welcome to WordPress Trac! Thanks for the report.

 > Anything changed in handling phpmail function from 5.5?

 In WordPress 5.5, the PHPMailer library was updated from version 5.2.27 to
 6.1.6, see [48033] / #48033. This was a major update with a lot of
 changes, so any plugins working with emails might require an update for
 compatibility.

 Does the issue still exist if you update Gravity Forms and all the other
 plugins to the latest versions?

 Setting the Version to 5.5 as the earliest applicable version.
