Hi, I got this message on a 2.1.4 system upgraded to 2.1.6 system with only the contact page package installed. This package is installed on every system we have and is not the issue. The other suggestions in this thread do not help, the email system was working fine before the upgrade. This is a test system and the issue cannot be reduced to other mods. It is a SMF code issue that this is not found.

I installed the SMF 2.1.4 system and this issue does not present when sending an email with the same MOD installed.
