Amazon SES for STMP - UTF8 error

Reporting an Issue
1

Hello,

When we add a special character in the title of an email (like New fax Received), Amazon SES will not process/send the message, and return this error message:

image

Action: failed
Status: 5.6.7
Diagnostic-Code: X-Postfix; SMTPUTF8 is required, but was not offered by host

For example, the title that was giving the error was:

image848×58 2.22 KB

If I replace the “ç” with a “c”, the email is accepted and processed by Amazon SES.
Email body with special characters are totally fine though.

Thank you for considering this issue for the next release of VitalPBX.
