[DUG]Sending email software

[John Bird]

Distributing software....

I am favouring making a self installer using inno-setup (a nice Delphi based
free installer).  This means sending a .exe file, which lots of email
systems will block, so I was thinking of sending the .EXE inside a .zip
file.  Will any email systems block a zip with a .EXE file inside?  (I think
some antivirus programs do look for this combination).  

Alternatively I could send the .EXE with a .DAT extension and get it renamed
after the attachment is saved..

What do others do?
