The dreaded gmail 550-5.7.1, I know it well. I had an account get compromised on Christmas day, and my server got blacklisted by gmail and others. There is nothing you can do, gmail will eventually delist you if the spam stops. I think that the sales emails are causing the problem here. I would have him consider either a dedicated server or using something like Constant Contact to send the mails. The place where I work uses CC for sales emails specifically to keep our mail server off blacklists. -- Mike McGinn KD2CNU Ex Uno Plurima No electrons were harmed in sending this message, some were inconvenienced. ** Registered Linux User 377849
