Thank you for clarifying this. But, now i have another question. If I try to connect via telnet to mx.kasakoff.net port 25 (from mx.kasakoff.net of course), my connection is not "automatically" authenticated. but, when sending mail via "mail" program, it works. Here is some log information: Mar 16 22:52:21 mx smtpd[13842]: 165f8a5170b2254b smtp connected address=91.210.228.4 host=mx.kasakoff.net - not sending to world Mar 16 22:54:43 mx smtpd[13842]: 165f8a5289de9eec smtp connected address=local host=mx.kasakoff.net - sending to world what is address=local? is this smtpd.sock? I cannot understand in what moment connection automatically authenticates.
