Billion ADSL/3G Router SMTP Server

[gmansa]

I have Billion 7402NX router setup with ADSL as main connection and a 3G fallover. Everything works great, the only thing I'm stuck with is, I have a mail server that usually (while on ADSL) relays mail to smtp.isdsl.net. But now when the modem switches over to 3G obviously that SMTP will not work.

My hopes were that on the Billion I will be able to accept SMTP traffic and then reroute it to the current active connections matching SMTP, havent had any luck with that.

Any order suggestions, PLEASE??!!

use smtp authentication

use smtp authentication

thanks, but unfortunately the linux servers in question don't use authentication when they relay mail

This is why I use Gmail SMTP servers instead, since they work on pretty much any connection...

But how do you use without authentication

You can't use the Gmail SMTP servers without authentication of course. Why is that a problem?
