hi,
Hi, lists.ripe.net is a simple CNAME to mamba.ripe.net without own MX records Any mailserver will try to deliver mail directly to the A record, if there are problems with the reachability of the zone, the network or the main MX records (and surely he will cache this descission). There were network issues, like RIPE NCC told me. Maybe its time to have a fallback MX for the subdomain itself ? That are pointing to postgirl.ripe.net and postlady.ripe.net ? So that no mailserver ever thinks to send mail directly to to the A record ? Just an idea .... Kind regards, Frank

will receives this could please make a telnet mamba.ripe.net 25 from some IPs he own (best would be not using his or her usual IP, if he or she likes, lets see how big that problem really is, thats why I have to mail the most active people directly).
suresh@frodo 03:54:25 :~$ telnet mamba.ripe.net smtp Trying 2001:67c:2e8:11::c100:1328... Trying 193.0.19.40... telnet: Unable to connect to remote host: Connection refused
Things seem to be RIPE for a change eh?
So, what exactly causes the assumption that mamba is supposed to be reachable from the outside, on Port 25?
$ host -t mx ripe.net ripe.net mail is handled by 250 postlady.ripe.net. ripe.net mail is handled by 200 postgirl.ripe.net.
Now, obviously, expecting anti-spammers to understand about MX records and how to read Received: lines might be asking for a bit much...
