Hi Wietse,
Thanks for getting back to me.
1) Its a connection to port 25587; a substitute for 587 (see (2) below)
2) Its behind a haproxy box, which in turn is behind a NAT router. I
haven't implemented postfix (yet)
3) inet_protocols = ipv4
Relevant line from mastr.conf:
25587 inet n - - - - smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_upstream_proxy_protocol=haproxy
I *think* things are working OK ie mail is flowing into and out of the
system (its still in "prototype" testing) - its just the logs are
filling up with the OP error message

Hi All,
I need some help in interpreting the following postfix log message,
please (this is showing up all over the log):
`Feb 24 17:46:55 mail postfix/smtpd[77980]: fatal:
smtpd_peer_hostaddr_to_sockaddr: cannot convert client address/port to
string: Servname not supported for ai_socktype`
The getaddrinfo(3) system library function cannot convert a (presumably
numerical IP address and numerical port) for the socket type
SOCK_STREAM into the internal form "struct addrinfo", and returns
the EAI_SERVICE error code.
I've looked online but I can't find an exact match and I can't work out
the problem (or, more importantly, how to fix the problem) from the near
and not-so-near google matches.
I'm not sure what to include re: (other) logs, config files etc, so
please feel free to ask if required? :-)
1) Is this a connection to port 25, 587, 465?
2) Is this a direct connection to an smtpd(8) process or is it first
accepted by postscreen, haproxy, or (nginx+)xclient?
3) What is the output from "postconf inet_protocols"?
Wietse
