Bloated Incoming Message Size

Hey everyone,

Recently a couple of users brought to my attention messages they are receiving from a reoccurring customer are in the 2-3 MB size per message. However when they forward the message including attachment it is reduced down to approximately 110k.
Upon investigation I broke some of the incoming messages by header, body, and attachment. With the header I copied the contents and saved it to a text file, the body I copied the contents and saved it to a word doc, and finally the attachment I saved as it originally came. The three items broken down and seperated in files came to a total of appox. 110k.

Is there a way to explain why an incoming message would be 3MB when it is in fact only approx 110k?

As you can imagine over time these incoming messages can accumulate and create a space issue on a users mailbox. Can any one recommend changes I can make to reduce the size of the incoming messages?

I am thinking there could be a change made to the transport or maybe I need to make an addition to the internet message types in Global Settings.
I would appreciate your opinions on this matter.

Keith

without writing a custom smtp event sink to handle this - the best you can do is to limit the size of the emails your system accepts

as for why a 3MB message can be rendered down to 110k? without actually examining the problematic message and looking at how it has been encoded, I couldn't begin to hazard a guess

Abhaigh,

The encoding is below.

Also I noticed in the header the UserAgent is Thunderbird. Have you ever heard of this?


--------------020700020309090100080705
Content-Type: text/html; charset=ISO-8859-15
Content-Transfer-Encoding: 8bit

--------------020700020309090100080705
Content-Type: application/msword;
            name="46532A.doc"
Content-Disposition: attachment;
            filename="46532A.doc"
Content-Transfer-Encoding: base64

thunderbird is the email client from the mozilla suite of programs

and have you checked the inbound message headers? I'm wondering if there isn't some large bcc: list attached to it (just a thought)

abhaigh,

So if it is a large BCC list how is that hidden in the email header?
