Hi, does anybody know how can i check which mailserver is running on my linux machine???

I need to know because i need to load a Spam filter.

Please help.

my Linux skills aren't of the best.

Thanks

You're likely to have either sendmail or postfix, they're probably the most common. Exim and qpopper are two other that I can think of at the moment.

If the mailserver is running, you can check which it is from command line with ps aux.
