You userdb seems to be incomplete.

,--[ http://wiki2.dovecot.org/UserDatabase ]--

| The user database lookup returns these fields:
|
|  * uid …
|  * gid …
|  * home …
|  * mail …
| …
`--

See the last example in
<http://wiki2.dovecot.org/AuthDatabase/PasswdFile>. The password line
for user armor5 would be:

armor5:{plain}abc123:1001:1001::/home/armor5

`mail' can be left blank, since you've configured mail_location.
