The problem is that you are an "open relay", which means that you let anyone who wants to send mail through your mail server. The ISPs you are referring to do not want to accept mail from people who charge their users to send mail, but allow spammers to send mail for free. To prevent this from happening, you need to "lock down" your mail server, so spammers can not use it for free. You need to use IMail's "Relay for Addresses" option (entering a list of "safe" IPs that your users may be coming from), or "No Mail Relay" (in which case everyone has to use SMTP AUTH before sending outgoing mail). -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com ______________________________________________________________________ The HKSI-IMail Admin List is hosted by........
