I am using Centos 5.7, and I have postfix installed.
So, I need to configure postfix and create a mail account via postfix. That mail account I have to put in alerts.cfg.
I hope that I understood you well. If I am wrong please correct me.

You need just regular sendmail working
on the host.
If You can send e-mail from OS with
mail or mails - then it should work for XyMon too (sometimes You may also
need to adjust sendmail configuration for masquarading, SMTP gateway etc).
Contact Your system administrator or
check web for "how to setup sendmail on linux or unix".
