=20 shows up in my messages

[fostergr]

I have an exchange 2000 server running on Win2K. Each has all the latest service packs and patches. I send many emails to text messanging servers like vtext.net and tmomail.net, etc. My problem is that all works well except for the messages to tmomail. They display on the phones with an "=20" at the end of each line. I'm guessing this is a replacement for the carrage-return/line-feed. It only does it on tmomail.net. When I send from another server to tmomail, the messages come through fine. It has to be something between my server and tmomail's server. But what? Where should I start looking for an answer? I'm using plain text in Outlook when sending. Plus, I've tried using different workstations to no avail.

Any help or suggestions are greatly appreciated.
