Test the mail function

[haeman]

I have some unix-like servers that use "sendmail" to transfer mail from the server to our lotus notes mail server , there are many mail are transfering every day from all unix-like servers to notes server . To test the mail function is normal , I have a stupid script to send a mail from each server to my lotus mail server , then I receive and count all these mails , if all received , that I sure the transfer is complete and mail function is normal , but this method seems not intelligence , can advise what is the better way to test it ? thx

What are you using to send the email to the Notes server?
