<p class=MsoNormal><span lang=EN-US>This is not exactly a MS related issue but mta
related, anyway I’ll post it here and u guys let me know what to do..<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>When I telnet port 25 in some sendmail
servers (all I tried) also postfix and even ms exchange I can send mails
with no authentication (using smtp commands), all the cases internal mails but also
can relay to external accounts. In both cases I can send mails via mail client (outlook,
Eudora etc.) just defining the account and leaving blank the password field,
even if I have to authenticate the users in order to send email.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Had anyone else see this kinda behavior? It
is the default normal behavior or it is a bug? I will appreciate your comments.<o:p></o:p></span></p>
