I am no sendmail expert either (nor am I expert of any kind :) ), but what you 
want is maybe called Smart Host in sendmail ?  Please take a look at that and 
see if that what you want. I think what SmartHost do, it will forward the 
mail to your publicly accessible (real) mail server  or www from your 
internal mail server, which then relay it to the pager host.
Something like:

define(`SMART_HOST',`smtp:smtp.harrisburgpa.gov')dnl in sendmail.mc,

where smtp.harriburgpa.gov is your external / real mail server. 

I am maybe way off, but check on the mailing list archive or google.
