I got requested to fix a machine with OE 6 that couldn't send mail.

After some experimentation, I found that only when using HTML format would the "send" fail by timing out. This took awhile to find because if I only sent a single word in the message, it would send. However, if I tried an entire paragraph, I got the time out message.

A repair of IE didn't give results I needed and the local ISP said they weren't having any problems with their mail server.

I'm at a loss as I've always used plain text. Any ideas on some things to try?

TIA
