Greetings,

I'm using Postfix 3.3.1-1+b1 (Debian testing).

I'm testing out the default for myhostname and am a little confused as to
where it is getting its value. I purposefully did not set it in main.cf:

# grep '^ *myhostname' /etc/postfix/main.cf || echo nope
nope

Here is what postfix believes myhostname to be:

# postconf myhostname
myhostname = net-services.localdomain

I would expect:

myhostname = net-services.d.umn.edu

Where is the ".localdomain" coming from?

# hostname
net-services

# hostname -f
net-services.d.umn.edu

# cat /etc/hostname
net-services

# grep localdomain /etc/hosts || echo nope
nope

Thanks for any help!
