But my real problem is a message being sent from BOA each morning and generating this error... Your message did not reach some or all of the intended recipients. Subject: LCM Summary Sent: 6/2/2010 10:18 AM The following recipient(s) could not be reached: robert(a)webtent.com on 6/2/2010 10:19 AM You do not have permission to send to this recipient. For assistance, contact your system administrator. <crprdnbrd10.bankofamerica.com #5.7.1 smtp;550 5.7.1 sscrivener(a)lcmgroup.com Not Authorized To Send Internet E-mail> sscrivener(a)lcmgroup.com receives this error message in the Exchange mailbox each morning and I can find this message in our Postfix logs at the gateway. But I cannot find any attempt previous. I can send these on demand, so I did and just this message came through the gateway. What can I take from this error message to help me track down why BOA is, evidently, generating this message? This is when we enter the recipient address in their alert system while loged in as sscrivener(a)lcmgroup.com. There is no SPF record for lcmgroup.com. I'm assuming this has something to do with Exchange, but why can I not see the original attempt to send the message in my gateway logs? Thanks for any help, Robert

Usually the error message contains info about "mailserver generating this message". If you don't see that sender on your postfix gateway, then I guess it's your internal exchange server. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de
