It might be related to the MTU size, particularly if you are using a
router.

After hours more of testing I find that the TRUE problem is different
but was masked.
In fact I can send messages that are under about 80K total size no
matter if text or jpgs. Above that approximate size they crash server
even if plain txt. Me thinks its phone lines now but going back to ISP
help tech again. Will post cure, HOPEFULLY.
Thanks again

Using XP and IE6 I can send text message to anyone or myself but if I
add attachment or in line JPG it will not go out. Server error, been
working with my ISP support over one hour with no progress.
Anyone see this before and know what's up?
