ESA Add Subject Line for emails without Subject Header

When emails are send from Iphone (Icould Account) without Subject line then that email will not have the Subject Line part in the Mail header, because of the same we will not be able to Add [EXTERNAL] TAG for that email. All other email are getting [EXTERNAL] because header contain Subject: Part. 


Please let know if there is any solution for this.

 

Thank you,

Vishnu

Does not appear to have condition for this in content filters.

 

You can try testing with the below message filter condition to see if that works for you.

 

if NOT(header("Subject"))

 

with action

 

insert-header("Subject", "")

 

It should basically look if Subject header is present, if not insert one.
