Sendmail K command regex: adding exclusion/negative lookahead to regex -a@MATCH
I'm trying to get some exclusions into our sendmail regular expression for the K command. The following configuration & regex works:
So we are blocking anything@subdomain.domain.us but not anything@domain.us. I'd like to add exclusions for cities and schools so to allow user@ci.somedomain.us and user@subdomain.[state].us. (note that [state] means 1 of the 50 states including DC).
This regex with negative lookahead syntax is not working (using CA for California as a test):
I get this error:
I'm pretty sure that sendmail's R & K commands do not support negative look-aheads. So if anyone can help re-write the regex in a sed-friendly format I'd be grateful! Here is a link to K command switches. Any suggestions on how to get the negative lookahead to work in sendmail?

What do you think of this regex to match IP address? I have been reading up on regex and have seen some really long ones for IP. Would this fail in any scenarios?

sendmailconfig
SENDMAILCONFIG(8) System Manager's Manual SENDMAILCONFIG(8)NAME
sendmailconfig - configure sendmail for Debian systems
SYNOPSIS
sendmailconfig [--no-reload]
DESCRIPTION
sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems.
In the simplest case, you may run this program to (re)configure sendmail for your Debian system at any time. It will modify the file
/etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf.
For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of sendmailconfig will
preserve these changes provided they are made at the end of the file.
Normally sendmailconfig will ask if you want to reload sendmail after making changes to its configuration. The --no-reload option will
avoid this question.
FILES
/etc/mail/sendmail.mc
sendmail m4 input to generate sendmail.cf
/etc/mail/sendmail.cf
actual sendmail configuration file
/etc/mail/sendmail.cw
names for which we will accept mail in the standard configuration
/etc/mail/sendmail.ct
names of trusted users in the standard configuration
