I run a mailing list and have a user @f41a1.com that informed me that he
isn't receiving list mail. Looking at both of my mail servers for
dcptech.com I have a number of emails backed up to him. Both
ironport.dcptech.com 199.212.124.13 and ironport-c300vb.dcptech.com
199.212.124.14 can't reach mail.f41a1.com 65.108.229.46 on TCP/25. Can
ping the server, but traceroute, traceroute tcp 25, and telnet 25 all
fail. Traceroute is dropped at
ex9k1.dc1.hel1.hetzner.com (213.133.119.3) 125.332 ms 125.218 ms
125.419 ms
I've tried testing from my 2 mail servers and 2 other systems within
199.212.124.0/24 with the same results.
Don't see my servers on any blocklists via mxtoolbox.com,
multirbl.valli.org and dnsbl.info.
