Essential Email Headers

[schilly]

I'm in the middle a revamping a newsletter system which is fairly old. I was just wondering if there is any essential mime headers that should always be set. Here is the headers of one of our current newsletters:

 

Return-Path:

Delivered-To:

Received:

Date:

To:

Subject:

From:

Reply-To:

MIME-Version:

X-Sender:

X-Priority:

Message-ID:

X-Mailer:

 

Any others I should add in?

 

thx.

That looks pretty inclusive - actually it's a bit more than the average.  I tend to only do five headers:

 

Date:

To:

Subject:

From:

Reply-To:

 

That of course depends on the importance of the message.  As a general rule, more headers (that are relevant) tend to do better with spam filters...

yea I think some of those were added by the mail server.

That does happen a lot, depending on what you're using for sending mail.  In general I think you'll be ok though.
