E-Mail subject string length

Solved1.15K views13th July 2023email notifications alarms notifications

Hello Dojo,

is there a way to modify the length of the e-mail header for e-mail notification sent by an DMS? For relatively long parameter description the subject does not show the full parameter name. Thus we have to open the mail to see the full parameter name. It would be great, if this would be directly visible in the mail subject string.

Many thanks for any hint

At the moment there’s still a hard coded limit of 78 characters.

This limit is the line limit as defined in RFC 5322 section 2.1.1. However, reading further in RFC 5322, section 3.6.5 says that the subject field is unstructured and can be spread over multiple lines (2.2.3), so the subject field doesn’t have a limit defined. Although it looks like Outlook and other clients apply a 255 character limit.

So we could investigate further if we can increase this limit. You can create a task on Collaboration for this.
