Hi all,

I did not recognize that 587 is only listening onIy on IPv4. Maybe it's
new, maybe it was alltime so.

sendmail  25090        root    4u  IPv4 0xfffffe01e810f3d0      0t0   
sendmail  25090        root    5u  IPv6 0xfffffe01a988f000      0t0   
sendmail  25090        root    6u  IPv4 0xfffffe011c53d000      0t0   
TCP *:587 (LISTEN)

FreeBSD 9.1-STABLE #8 r248707

freebsd.submit.mc states:

dnl If you use IPv6 only, change [] to [IPv6:::1]
FEATURE(`msp', `[]')dnl

But IPv6:::1 makes no difference, same picture only listen v4.

hostname.domain.com grown over the years. TLS, some milters, SRS Hack.
And working fine so far.

Any hint for me?

kind regards,
