One user in my company reported me an error when he's trying to send an e-mail for a mailing list.
firstname.lastname@example.org on 17-07-2008 12:07

<CESCESMTP01.cescesi.pt #5.7.1 smtp;550 5.7.1 Unable to relay for email@example.com - reinject host refused rcpt to: - psmtp>
The user is trying to send an e-mail for about 50 different destinations at the same time.
Do you an answer to solve this problem?
