what is the most common MTA installed in YDL

[oeboeroe]

I was wondering what the most common MTA is used in YDL installs. I am writing up a simple howto for postfix on YDL to setup a secure way of mailing through gmail.

If there are others out there intrested and not running postfix, I could include exim and sendmail just the same.

Maybe even wrap this up in a simple python script so anyone can set it up.

Let me know.
