Re: sendmail



If you want sendmail to authenticate with Rogers (required to send mail via Rogers) then you need to use sendmail's access database option. Put the following line in the access file with a valid user rogers com and password. Don't forget to run a makemap command to create the access db file properly. The sendmail.mc file needs to have the proper feature command to enable the access file.

AuthInfo:smtp-rog.mail.yahoo2.akadns.net "U:user rogers com" "P:user_password"

Then add the following line to sendmail.mc

define(`SMART_HOST',`esmtp:[smtp.broadband.rogers.com]')

There's lots of sendmail config HowTo's explaining how to set up the config files. Just use the above Rogers specific info. I suggest you use fetchmail to pull email from the Rogers server. It's easy to setup.

It's against Roger's end user agreement to run a server on their network. They actively scan for servers and will threaten to discontinue your service if they find one. Also, Rogers uses dynamic ip's. Their range of ip addresses is checked by programs like spamassassin and your email will be discarded if found to come from within their range. Just use the smart host feature and pull incoming mail from their server. It will make your life much easier.

Ahmed,

Try tcptraceroute. you can use tcptraceroute utility to trace where is the
port 25 blocked.
you may need to download a rpm package for tcptraceroute and install it.

I have heard that Rogers does not allow running servers on home internet. I
believe Bell does.

Thanks

Thanks Jeremy L. Gaddis and all.

I was suspecting all along that the problem might be with outbound port 25
blocked but I was not completely sure. To get around the problem, I have
since tried other ports like cyrus2 587. In addition, I configurered
SMART_HOST with  (`smtp.broadband.rogers.com')dnl   (I am not sure if it
is
correct the
one - Rogers folks would'nt tell you). No luck.

By the way, does anyone know of CANADIAN ISP provider that allow
port-forwarding
like mail, http, and the like. Your suggestions are welcome.
