Each mail service has their own rules.
Sounds like Yahoo's rules for attachments are a little less restrictive.

Hello group,

I was having some trouble transmitting an .exe file via Windows Mail. I
received some helpful suggestions. Thank you.

Just curious about one more thing: Yahoo mail doesn't seem to be bothered by
.exe files at all. I am able to transmit these files via Yahoo mail with
ease. Does anybody know why .exe files can't be transmitted by Windows Mail,
yet there's no trouble with Yahoo mail?

Just curious.

thanx
