I have set up a postfix mail server behind a NAT.  Am using a static 192.16=
8 IP address, and have port 25 forwarded to that server.  Also am using out=
going.verizon.net as a relay host,  (And dovecot to provide IMAP service, b=
ut it's not running while I test this.)  I am able to receive and send mail=
.  The problem is, in sent mails, the sender has no host name.  If I send a=
 message from user1 to a Yahoo account, the mail is received, but the From =
field has "user1@.MISSING-HOST-NAME.".  If I send a message to a local user=
 (user2), the mail is received, but the From field has "user1@".  I don't s=
ee what is wrong in the configuration.

I'm not even sure it's a problem with postfix, but what else could it be?  =
I'm using Arch Linux, and they've recently switched to systemd.  Could syst=
emd be messing it up somehow?  I've been testing with mutt and alpine, coul=
d either of those be causing this problem?

I edited /etc/hosts, so "hostname -f" reports "mail.example.com".

---------------
Here's my /etc/postfix/main.cf:


queue_directory =3D /var/spool/postfix

command_directory =3D /usr/sbin

daemon_directory =3D /usr/lib/postfix

----------------------------
Here's what I think is relevant output from postconf:

append_at_myorigin =3D yes
append_dot_mydomain =3D yes
mydestination =3D $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain =3D example.com
myhostname =3D mail.example.com

mynetworks_style =3D subnet
myorigin =3D $mydomain


----------------------------
And here's what I see in the logs when I send a message from user1 to user2=
:

I've tried several postfix configuration options, and had no luck:

masquerade_domains =3D $mydomain
disable_dns_lookups =3D yes
smtp_host_lookup =3D native
resolve_null_domain =3D yes


Anyone have any ideas what I'm missing?
