I have problem with notification system on itop. Some of my automatically generated messages cannot be delivered to some e mail addresses. Often connected with gmail accounts. The emails are 100% existing and correct. I suspect it is a problem with UTF-8 format in message id. Does anyone have idea how to change it?
Thank you in advance for your support
I get notification like that:
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

Perhaps a recent change on Google?
In Microsoft Outlook (desktop) the sent item shows this as message-id:

According to quick research (to double-check) - the MIME encoding would not be allowed for this header (RFC 5322).
