I'm going to try sending this from Yahoo to see whether it will get through. Bendel seems to be having some issues. I don't know whether Yahoo will mangle the terminal commands. I apologize in advance if it does.
A message that I sent from my primary email address this morning was stuck in the outgoing queue: # mailq -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- D9EDA819CA 2475 Wed Feb 18 07:08:40 [email protected] (connect to bendel.debian.org[2001:41b8:202:deb:216:36ff:fe40:4002]:25: Connection timed out) [email protected] -- 2 Kbytes in 1 Request. # host bendel.debian.org bendel.debian.org has address 82.195.75.100 bendel.debian.org has IPv6 address 2001:41b8:202:deb:216:36ff:fe40:4002 # ping 2001:41b8:202:deb:216:36ff:fe40:4002 PING 2001:41b8:202:deb:216:36ff:fe40:4002(2001:41b8:202:deb:216:36ff:fe40:4002) 56 data bytes ^C --- 2001:41b8:202:deb:216:36ff:fe40:4002 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 1005ms # ping 82.195.75.100 PING 82.195.75.100 (82.195.75.100) 56(84) bytes of data. 64 bytes from 82.195.75.100: icmp_seq=1 ttl=47 time=86.8 ms 64 bytes from 82.195.75.100: icmp_seq=2 ttl=47 time=86.7 ms ^C --- 82.195.75.100 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 3ms rtt min/avg/max/mdev = 86.717/86.773/86.830/0.299 ms So, I configured Postfix to use only ipv4, and now: # postqueue -f # mailq -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- D9EDA819CA* 2475 Wed Feb 18 07:08:40 [email protected] (host bendel.debian.org[82.195.75.100] said: 450 4.7.25 Client host rejected: cannot find your hostname, [199.231.184.176] (in reply to RCPT TO command)) [email protected] -- 2 Kbytes in 1 Request. However, I do have a working "reverse DNS" on this host. It was configured last night (8-9 hours ago); $ host 199.231.184.176 176.184.231.199.in-addr.arpa domain name pointer wooledge.org. A message that I queued up the other day and which was being rejected for the same reason did manage to go through successfully after that. I don't know what's going on with bendel, but I hope it gets fixed.
