Mailertable *is not* consulted => most likely  simutronics.com is on list of 
local email domains (mailertable *is not* consulted for local email domains) 
Sendmail selects "local" mailer set by the following line in *.mc file:
	define(`confLOCAL_MAILER', `cyrusv2')dnl

To get list of local email domains use:
echo '$=w' | sendmail -bt

You see the line below at work:
	define(`confLOCAL_MAILER', `cyrusv2')dnl

Fixes:
A) Stop sendmail "automagically" add names to list of local email domains set 
DontprobeInterfaces option to True.
http://www.sendmail.org/m4/tweaking_config.html#confDONT_PROBE_INTERFACES
In such case you will have to configure list of local email domains 
"manually". How to add domains to list of local email domains is described 
(among other things) at http://www.sendmail.org/faq/section4.html#4.5
Make sure that simutronics.com is not listed as local email domain

OR

B) Do not play with Dontprobeinterfaces, use "Local Relay" (or "Luser Relay") 
variant of RTCyrus2. Remove "define(`confLOCAL_MAILER', `cyrusv2')dnl" from 
*.mc file.
