I think your problem is that for Cyrus virtdomains to work the MTA needs
to send the _full_ address in the LMTP transaction. When Sendmail
speaks to Cyrus lmtpd, it needs to say
RCPT TO:<boo at yo.com>
rather than just
Sendmail's definition of the cyrusv2 mailer
(/usr/share/sendmail/cf/mailer/cyrusv2.m4 on Debian, possibly elsewhere
on FreeBSD) sets "R=EnvToL/HdrToL", but for virtdomains you want
"R=EnvToSMTP". It's also recommended that you change
"S=EnvFromSMTP/HdrFromL" to "S=EnvFromSMTP/HdrFromSMTP".
As a quick hack, you can change those in situ; or - more gracefully -
you can define a new mailer which works this way and use it instead.
The Open-Sendmail project has bells-and-whistles implementation,
cyrusv3.m4, within RTCyrus3:
but it is quite complicated to install.
It's not clear to me what the above lines are achieving when you also
have the below:
