dumb question: if I get 'connection closed' as below, does that confirm problem is at remote end, not my Postfix ?
is there any other diags I can run from my end ? Postfix works well, but, can not send to one particular server from my Postfix server, I get telnet failure as so: # telnet 115.70.161.114 25 Trying 115.70.161.114... Connected to 115.70.161.114. Escape character is '^]'. 554 No SMTP service here. Connection closed by foreign host. from a Win box on another network I get though >telnet 115.70.161.114 25 220 rosscosmetics.com.au ESMTP Trustwave SEG Ready ehlo sbt.net.au 250-rosscosmetics.com.au Hello sbt.net.au (110.175.246.167) 250 SIZE help 214-Supported commands 214- EHLO HELO MAIL RCPT DATA 214- VRFY RSET NOOP QUIT 214- 214- SMTP Extensions supported through EHLO 214- HELP SIZE AUTH 214- 214 End of HELP Info
