Summary0003939: Generated emails cause some email scanners to report false virus positives
Description

Some email scanners will report the emails generated by mantis to potentially contain a virus, and quarantine them.

Additional Information

This is due to declaring Content-Type and not declaring the Mime-Version.
Changing line 712 of email_api.php to: $t_headers .= 'Content-Type: text/plain; charset=' . lang_get( 'charset' ) . "\nMime-Version: 1.0\n";

Fixes the issue.

The MIME-Version header should set by PHPMailer library, on any outgoing mail sent by MantisBT.

We are resolving this issue as "no change required", because it was reported against an old version of MantisBT which is no longer supported.

We recommend that you upgrade to the latest stable version [1]; if the problem persists after doing so, do not hesitate to reopen the issue.
