Does enp1s0 have an associated inet4/inet6 address? I tried debugging
here, and observed that I can start smtpd with it listening on an
interface only if that interface has an address. Here's what happens
when I assign my (unplugged ethernet) interface eno1 a bogus address and
try to start smtpd, versus what happens when I try to start smtpd when
eno1 doesn't have an address associated with it.
rak@zeta:~$ grep eno1 /etc/smtpd.conf
listen on eno1
rak@zeta:~$ sudo ip address flush dev eno1
rak@zeta:~$ ip addr show eno1
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state
DOWN group default qlen 1000
link/ether 20:47:47:ae:78:79 brd ff:ff:ff:ff:ff:ff
rak@zeta:~$ sudo smtpd -n
invalid virtual ip or interface: eno1
rak@zeta:~$ sudo ip addr add 123.123.123.123 dev eno1
rak@zeta:~$ ip addr show eno1
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state

link/ether 20:47:47:ae:78:79 brd ff:ff:ff:ff:ff:ff
inet 123.123.123.123/32 scope global eno1
valid_lft forever preferred_lft forever
rak@zeta:~$ sudo smtpd -n
configuration OK
rak@zeta:~$ sudo ip address flush dev eno1
rak@zeta:~$ sudo smtpd -n
invalid virtual ip or interface: eno1
Best wishes,
Ryan
