Issue/Introduction

Some notification messages sent from PGP Encryption Server are not received by external recipients when a non-English message template is used or if the English message template is used but the email message contains non-English characters.

Environment

PGP Encryption Server 11.0.0

Cause

The remote mail server does not support SMTPUTF8.

If you navigate to Reporting / Logs and select the Postfix log you see entries like this where mailhost.example.org is the mail server that PGP Encryption Server is routing notification messages to:

85327F02: to=<[email protected]>, relay=mailhost.example.org[10.10.10.10]:25, delay=0.02, delays=0.01/0/0/0, dsn=5.6.7, status=bounced (SMTPUTF8 is required, but was not offered by host mailhost.example.org[10.10.10.10])

Resolution

Ensure the mail server that PGP Encryption Server is routing notification messages to supports SMTPUTF8.

All modern mail servers will support SMTPUTF8.
