This is commonly used in workflow applications to send a notification of a change in state of a request. Here is the proper syntax:
@Mailsend("sendto"; "copyto"; "blindcopyto"; "subject"; "remark"; "bodyfield1":bodyfieldn"; [flag1]:[flagn])
I want to initiate an @Mailsend to a user in the author field of a document. I want to send him some info on an approved request. Here is the syntax I would use:
@Mailsend("John Doe"; ""; ""; "Your request is approved"; "If you have any questions, please let me know"; ""; [IncludeDocLink])
What actually happens is the remarks field and all the bodyfields (along with the doclink) get concatenated in the rich text field of the mail message.
