Dear Yuval: i'm not an emminence in this area, so i haven't the necessary knowledge to answer your question with totally authority... take this as a commentary from other user. The remote SMTP sends to your SMTP an e-mail, that is received. when this step is ended, then your SMTP moves the mail to the queue and only then starts the filtering process. In this concept, the communication between your SMTP and the remote SMTP has ended before the filtering starts, so the remote server can't give up with the sending process, because it's terminated with an ok status in a ok period of time (again, before the start of the filtering process). i am new in qmail and in qmail-scanner, so i cannot answer your question, i just tell you how i understand the mail delivery and filter process (generic, for every MTA). You may be need to read more documentation about this, so then you will have the authority to tell me "you have reason" or to tell me "you are wrong because ... (bla bla bla) ..." now i will sugest to look for other posible cause. i hope my mail will help you in some way byz! charly ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
