perhaps it cant find a ipv4 address for m1.volny.internal in your dns ?
what says
dig m1.volny.internal
on your mailserver
also you might set
inet_protocols = ipv4 in main.cf
inet_protocols (default: all)
The Internet protocols Postfix will attempt to use when making or
accepting connections. Specify one or more of "ipv4" or "ipv6",
separated by whitespace or commas. The form "all" is equivalent to
"ipv4, ipv6" or "ipv4", depending on whether the operating system
implements IPv6.
With Postfix 2.8 and earlier the default is "ipv4". For backwards
compatibility with these releases, the Postfix 2.9 and later upgrade
procedure appends an explicit "inet_protocols = ipv4" setting to main.cf
when no explicit setting is present. This compatibility workaround will
be phased out as IPv6 deployment becomes more common.
This feature is available in Postfix 2.2 and later.
Note: you MUST stop and start Postfix after changing this parameter.
On systems that pre-date IPV6_V6ONLY support (RFC 3493), an IPv6
server will also accept IPv4 connections, even when IPv4 is turned off
with the inet_protocols parameter. On systems with IPV6_V6ONLY support,
Postfix will use separate server sockets for IPv6 and IPv4, and each
will accept only connections for the corresponding protocol.
When IPv4 support is enabled via the inet_protocols parameter,
Postfix will look up DNS type A records, and will convert IPv4-in-IPv6
client IP addresses (::ffff:1.2.3.4) to their original IPv4 form
(1.2.3.4). The latter is needed on hosts that pre-date IPV6_V6ONLY
support (RFC 3493).
When IPv6 support is enabled via the inet_protocols parameter,
Postfix will do DNS type AAAA record lookups.
When both IPv4 and IPv6 support are enabled, the Postfix SMTP client
will attempt to connect via IPv6 before attempting to use IPv4.
Examples:
inet_protocols = ipv4
inet_protocols = all (DEFAULT)
inet_protocols = ipv6
inet_protocols = ipv4, ipv6
