Hi, I have a problem when I try to forward mails from my back up qmail server to MS Exchange server. that is if there are more than one mail in the queue that qmail try to flush out, qmail can only get one "/Remote host say 250ok " response with all mails go through( i got all mails). So it can only clean one mail out the queue but keep all the others and never try redeliver till i restart qmail, it resend all remaining mails get another 250ok ande remove another message from queue. 250ok appears randomly not always the first message that been delivered. May someone help me that what may cause this problem? Thanks for your help MinF
