I wanted to use symbols in the subjects of Alert Mail in order to have a faster view of things like up/down status. Using characters like these (▼▲) works well in Management Console notifications, but I have not been able to configure the server to send them so they appear in the subject line in e-mail clients. Note that I am able to paste these symbols into e-mail subjects and send them with the characters intact.
I have tried changing the value of the "MailEncoding" server parameter to utf-8, but I suspect (from looking at the email.cpp source code) that I need to make use of the "MailBase64Subjects" parameter. This parameter does not appear in the Server Configuration page in the Management Console, however, and setting it in netxmsd.conf did not seem to make a difference.
Can anyone tell me how to make this work?
