Lift Mailer: Email Threading: Adding Unique Email Headers

[Dan]

As part of a webapp, users can receive notification emails when users
reply to a given post. However, the emails are not currently threaded,
and I don't see how to add a unique header to notification emails that
are for replies to the same post. My goal is to have all replies
threaded together for a given post.

Adding a unique per-post subject and unique per-post reference header
could help solve this threading problem.

I've enjoyed working with Lift, but this has proved troublesome.

I appreciate the help.


Best,
Dan

Lift's mailer uses javax.mail - http://www.oracle.com/technetwork/java/javamail/index.html

Can you not do what you want with that?

Thanks Tyler.

I wanted to see if a strategy for this already existed within Lift. I
could go about and build my own Mailer class, but I was checking out
Mailer (
http://scala-tools.org/mvnsites/liftweb-2.0-M3/framework/lift-base/lift-util/scaladocs/net/liftweb/util/Mailer.scala.html#Some(31)
) which creates the conventional headers, though I wanted to add my
own.


Any other thoughts?

You can add a custom unique per-post subject easily enough:

Mailer.sendMail(From("y...@example.com"), Subject("whatever you like here"), To(som...@example.com"), msg)

But I don't see an easy way to add a custom Message-Id, References and/or In-Reply-To header for an outgoing email. Maybe someone else can spot how to do it, otherwise it does sounds like a useful addition.  Perhaps a HeaderType (key->value) to add to MailTypes?

Sounds good.  Please open a ticket and assign it to me.

Hi Dan - just to confirm, being able to set headers is all you need?

Cheers

Right, what you mentioned in your first message is what I need:
ability to set headers: ( " custom Message-Id, References and/or In-
Reply-To header for an outgoing email " ).

Though, did you have any other capabilities in mind related to
threading emails?

Thanks for the help.

(Also, once we are confirmed, should I file the ticket?)


Best,
Dan

Hi Dan - I don't have anything else in mind.   If you wouldn't mind creating the ticket, that'd be good, as it sounds like you're in a position to try it when it's done. See http://www.assembla.com/wiki/show/liftweb/Creating_tickets

One comment: I was just looking at JavaMail 1.4, and setting Message-ID might be tricker than it should be as it seems to require subclassing MimeMessage to jump in on updateMessageID() to prevent JavaMail from setting its own ID if we try to set one first.

Richard,

All right, ticket (#953) created.

Thanks. Look forward to the enhancement!

Thank you - and I've assigned it to David as he requested.
