Our smpt-proxy somtimes returns mails with the message "connect failed

after repeated attempts for xxx@mail.com", but the origin mailer is
and I'm able to send mails to this address by a freemailer or telnet.The proxy already started with the option "-m".

Someone told me that I should not use the smtp-proxy and reconfigure
system to a generic proxy on port 25.

Do someone know how to do this, because older versions of bordermanger

does't allow to set up a generic proxy on port 25.

We work with Netware 6.0 SP2 and BM 3.7 SP2
