The gid could be a problem problem (if /var/mail was group-writeable).
See the "group" option for the appendfile transport.

As you see, the "group" option alone wouldn't help. You'd need to make
the directory group writeable.
On my 3.6 I have the same root-only-writeable /var/mail:
drwxr-xr-x 2 root wheel 512 Oct 1 15:00 /var/mail

Because mail.local stores temporary files in /tmp, as /tmp/local.*.

I don't deliver mail to /var/mail... On a couple of FreeBSD systems I
have enabled delivery to /var/mail, there I have
drwxrwxr-x 2 root mail 512 Aug 13 19:07 /var/mail
The transport for local delivery used is
driver = appendfile
file = /var/mail/$local_part
mode = 0660
user = $local_part
group = mail
You could create a group "mail", chgrp /var/mail to mail and chmod it 0775.
