Hi, thanks for reply. We thought that we have to copy existing "aliases" file from imap server to incoming MX. If we reject an emailduring smtp communication, we won't "relay" spam to victim. Am I right ? Best regards J.K. Cituji Mikael Bak : Hi Josef, On 04/18/2013 11:06 AM, Jo

Hi, Thanks for your replies. I know how to allow relay by its IP address but I'm just afraid that it would be easy to fake an up address and use my server as a spam relay. I would prefer to combine this with some form of authentication. Would you happen to know a good manual for setting up SASL
