How to test email of 80 domains daily

[wookiee]

Greetings,

I just have a reseller account with about 80 domains (mine).
Lately I've been having a problem with mail not coming through.
My provider tracked it down to the localdomains file and corrected it.
It's happened twice.

How can I test mail to all the accounts? I want to use one account name and one non-account name (to test forwarding) for each domain.

I've tried the email list supplied with cpanel as well as just putting all 160+ addresses in either the to:, bcc, or cc of a normal email.

Neither works because both ways don't put in seperate addresses in the To: of the email, which I need in order to see if it came through.

I hope that made sense.

You could use a mailing list. Or perhaps something like:
http://www.group-mail.com/asp/common/downloads.asp

Seems a bit of overkill really.

I just set the maillist to notify me after the first bounce.
I'll have my calendar send a message to the list once a day. This way I'll know within a day if there's problems with the mail.
