Hi,
Just got this error on one of our outgoing servers running Exim 4.89
(Debian Strech):
2018-11-27 00:34:42 1gRPih-0001GK-Vx == [email protected] <[email protected]>
R=dnslookup T=remote_smtp defer (-1): smtp transport process returned non-zero status
0x000b: terminated by signal 11
2018-11-27 00:34:42 1gRPih-0001GK-Vx Frozen
I used tcpdump listening at all the recipient MX addresses and forced a
retry with "-M" and I got this:
https://pastebin.com/YHEjpi3y
It seems some kind of tarpitting to me but I suppose Exim should handle
it gracefully and not freeze the message.
P.S. I'm aware the destination server has our server's IP in a blacklist.
Thanks.
Ruben Mendes
