Is the Swinog DNSRBL Whitelist at http://antispam.imp.ch/swinog-dnsrbl-whitelist still being maintained actively?
I use this list for our greylisting bypass filter and just had a case with a swisscom server that was not listed (which I would expect).
The server in question was 194.11.148.23 (outmail43.swisscom.com).
Or does anyone have a list of swisscom outmail servers?
Cheers,
Mike
