if all else fails, yahoo and hotmail accounts are free

It's not me. It's the other guy that has Gmail.
I just have to suffer with it.

well - make HIM get a free account at hotmail or yahoo - lol
make HIM do the suffering   :bg

What I do is : RAR the files with a password and set "encrypt file names" option
The truth cannot be learned ... it can only be recognized.

oh - i do use another approach altogether from time to time
i have a free file-share at http://www.4shared.com and put the file up there (there are several others like rapidshare, etc)
then, just e-mail them a link
that takes care of the g-mail issue, and allows for files larger than 10 Mb, as well
it does not, however, address the firewall issue that Hutch was refering to
changing the file type as Jochen suggested should fix that
long ago, i wrote a 16-bit program that xor'ed only the first 1 Kb of a file to make it look like garbage
then, it changed the file extension to something like A01, B02, etc, according to the original file type
the same program ran again would unhash the first 1 Kb and change the extension back
it was written to maintain the file date and time stamps
oh - it also altered the filename like a Drogan's decoder wheel - lol

I wrote a simple XOR encryptor to test my gmail account. The tool performs an XOR operation against all the bytes of any binary file :

encrypt sourcefile.exe destfile.ext encryption_byte

To encrypt :

encrypt.exe test.txt encrypted_test.txt 170

To decrypt :

encrypt.exe encrypted_test.txt test.txt 170

You can specify any other encryption byte. Change the extension of your executable, encypt it and send it via any email account.

It would be good to write a .vbs script to handle at least the encryption tool.

I tried usingĀ  7-zip. Came back quicker than a whistle.
Zipping it into another zip won't work as It will not accept Zip period.

Need a way in propertiesĀ  to change the .exe to jps or something.
Then a way to change it back at the other end.
Or get rid of GMAIL :bg

When using 7-zip, make sure to have it create a file with a 7z extension!  Using the default compression method that 7-zip recommends.

It's the fact that Gmail sees the .zip extension and examines the contents of the .zip file that causes the problem.  Gmail does not examine .7z files.  I do it all the time.  It has worked every time.

The only drawback is that the user has to have 7-zip.

i think g-mail looks at the file signatures
and, it may not recognize the 7Z marker now
but it won't be long before they put that one in the list
