Mick,

I have tried emailing to my own gmail account and so far I have not been
able to circumvent their security.

Checking for double messages ? Just add some random data into the (re)send
message. Most likely even a counter will do.

Checking if the send files are "dangerous" ? Change the first few bytes in
the (executable or ZIP, etc) file (take any hex editor and add one to each
letter A-B, B-C, etc. See Napoleons ring for that - and our modern ROT13
"encryption") so the file ID becomes unrecognisable (but reversable)*.

Ofcourse, by editing them that way your ISP gets exactly what it wants: The
considered-to-be-noobs on the other side (in this case: yourself) will not be
able to simply double-click and run them. :-)

*with just a little bit of luck you could do that with some VBScript or alike
- as long as it can handle binary data.

I am not that bothered Rudy, with messing around for something I will
not use very often. I was just trying out of curiosity. If I need to
send a file that gmail throws out there are other ways to get that file
to its destination.
