Re: [swinog] gprs01.swisscom-mobile.ch whitelisting / dsbl

Hi Oliver

Problem: some customers online via gprs are unable to send mails over these servers, because their external visible IP adress (gprs01.swisscom-mobile.ch: 193.247.250.1) is blacklisted on several lists:

Well known fact. We nearly spent hours with swisscom to try to find a solution. Unfortunately they do 'NAT' so they are not able to identify customers sending spam via gprs. It's also inpossible for them to change an ip-address. As far as we found out, each ip-address represents a roaming partner of swisscom.

Swisscom at least sent us the ip-addresses they use for gprs.

grep for 'grps' (sic), maybe it's going to be corrected in a few minutes :-)

Mit freundlichen Grüssen
