Or, would this work?
auth_advertise_hosts = localhost : ${if eq{$tls_cipher}{}{nope}{*}}
taken from:
http://serverfault.com/questions/617848/exim4-require-tls-for-all-hosts-but-localhost
Any downside?
Also, where/how to implement?

Thanks (again) Jeremy,
By any chance would you know either (1) which file I need to modify from the Linux command line or (2) which section in WHM's Exim Configuration Manager's Advanced Editor (see below) this code needs to be placed?
Sorry, I'm a total newbie working with Exim.
I see the Advanced Editor in WHM includes quite a bit of options. There is a section that already includes server_condition. I'll paste a little before and after where server_condition is located for reference:
...
Section: ENDACL
<there's a text area here to insert code>
begin authenticators
courier_plain:
driver = plaintext
public_name = PLAIN
server_prompts = :
server_condition = ${if and{{!match {$auth2}{\N[/]\N}}{eq{${if match {$auth2}{\N[+%:@]\N}{${look
up{${extract{2}{+%:@}{$auth2}}}lsearch{/etc/demodomains}{yes}}}{${lookup{$auth2}lsearch{/etc/demouse
rs}{yes}}}}}{}}{!eq{${extract{address}{${readsocket{/var/spool/authdaemon/socket}{AUTH ${strlen:exim
\{$sender_host_address\|$received_ip_address\}\nlogin\n$auth2\n$auth3\n}\nexim\{$sender_host_address
\|$received_ip_address\}\nlogin\n$auth2\n$auth3\n}}}}}{}}}{true}{false}}
server_set_id = $auth2
server_advertise_condition = ${if or {{def:tls_cipher}{match_ip{$sender_host_address}{+loopback}
}}{1}{0}}
courier_login:
driver = plaintext
public_name = LOGIN
server_prompts = Username:: : Password::
server_condition = ${if and{{!match {$auth1}{\N[/]\N}}{eq{${if match {$auth1}{\N[+%:@]\N}{${lookup
{${extract{2}{+%:@}{$auth1}}}lsearch{/etc/demodomains}{yes}}}{${lookup{$auth1}lsearch{/etc/demousers
}{yes}}}}}{}}{!eq{${extract{address}{${readsocket{/var/spool/authdaemon/socket}{AUTH ${strlen:exim\{
$sender_host_address\|$received_ip_address\}\nlogin\n$auth1\n$auth2\n}\nexim\{$sender_host_address\|
$received_ip_address\}\nlogin\n$auth1\n$auth2\n}}}}}{}}}{true}{false}}
server_set_id = $auth1
server_advertise_condition = ${if or {{def:tls_cipher}{match_ip{$sender_host_address}{+loopback}}}
{1}{0}}
Section: AUTH

server_advertised_condition = ${if = {$received_port}{26}}
