[Pkg-exim4-users] Use of primary_hostname with visiblename

[Bill Horne]

Because I have been trading emails with a system that demands perfect
forward/backward lookups on HELO info, I've changed the primary_hostname
of my Exim4 installation. 

I have Linux setup as billhorne.homelinux.org, but because that name
doesn't match the MX record assigned to my IP address, another MTA is
refusing to accept my mail. Ergo, I have forced Exim to use the A record
assigned by my ISP.

Since I want those I write to see "billhorne.homelinux.org" in my email
address, and not "dsl092-086-246.bos1.dsl.speakeasy.nyet"I also set the
"visiblename" option in update-exim4.conf.conf so that my "from" domain
would remain billhorne.homelinux.org, ran the update-exim4.conf and
restarted the MTA, but the change had no effect. However, when I put
in /etc/mailname and put billhorne.homelinux.org into that file, the
"From" addresses came out correctly.

Please tell me why visiblename isn't being set from the
update-exim4.conf.conf file. TIA.

Debian Sarge, Exim 4.50
