Re: outages mailing list is back online!
Not quite. Outages list traffic appears to be originating from 126.96.36.199, which has rDNS mx2.amigostecnicos.net, which has forward DNS 188.8.131.52, which does not match the originating IP. This inconsistency may cause deferral/rejection/quarantining depending on how recipients' MTAs are configured. For example, sendmail with require_rdns switched on responds with a 451 to this. I suggest fixing the DNS inconsistency. ---Rsk
