Our office is using a 3rd party hosting site for our email accounts (hostpapa.com.au) and we have one user that always takes around 3 times longer to send, receive his own emails, and for other users to send and receive to/from him as well.

We recently set up an "Out of office" auto response, which for some reason created a large amount of garbage text and added it to the email. I exported the email text to a .txt file, which ended up being 67MB. The message that was sent looked like this:

This is a multi-part message in MIME format. --------------000102020002060902000107 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit I am out off the office until 5th Jan, and will reply to your email when I get back. --

Sincerely

After this the text contained endless "/" and the occasional burst of non-sensical character streams like:

What could be causing this?

have a look at his signature. It probably has a 60mb image of him.

People forget that a 10 megapixel camera images needs to be compressed for use on the web or email. It is also most unwise to use a BMP file in email as it has no compression and uses one byte for every pixel.

It is also worth remembering that every bit if binary data included in an email is mime encoded so grows by about 30% by virtue of being attached or included. Images in commercial mail is almost always a linked remote image that is downloaded when the mail is read, from a web server. It makes the email lean and reduces the risk of non delivery through full inbox or exceeding the allowable size for a mail.

Hi Matt,

Unfortunately I know the signature isn't the problem. it's a small bmp of the company logo. Additionally (I thought I had mentioned this, but I seem to have accidentally omitted it) he sent me another blank email, with the same signature and it only turned out to be 211 bytes

the information you supplies indicate a BMP image, there is insufficient information to go further.
