Wrong? Was your statement, not mine. 465 is ssh and 587 for smtp submission. Port 25 is still used/usable if not blocked/hijacked by your isp, and then you can use a upper/higher port. http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol <quote> Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks. SMTP was first defined by RFC 821 (1982, eventually declared STD 10),[1] and last updated by RFC 5321 (2008)[2] which includes the Extended SMTP (ESMTP) additions, and is the protocol in widespread use today. SMTP uses TCP port 25. The protocol for new submissions (MSA) is effectively the same as SMTP, but it uses port 587 instead. SMTP connections secured by SSL are known by the shorthand SMTPS, though SMTPS is not a protocol in its own right. </quote> > > no, not so. And I can do the same from windoz.

But you are not limited to port 25 for outgoing mail. Assign a higher port, >1024. -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://linuxcounter.net
