Its been a few years but lets go:

add abcd1 at mydomain.com  and abcd2 at mydomain.com to /etc/mail/access
then give em access or denied rules :
abcd1 at mydomain.com REJECT
abcd2 at mydomain.com RELAY
makemap hash /etc/mail/access < /etc/mail/access

Does it work? If not, have you explicitly enterered you smarthost?
No, then install the m4 macroprocessor,
vi /etc/mail/sendmail.cf
define(`SMART_HOST', `your-smtp-server')
FEATURE(authinfo)dnl

More info on t'internet

Save and exit and then
m4 /etc/mail/sencmail.mc >>/etc/mail/sendmail.cf

Forgive me if this has errors but I have a few glasses of wine, hic...  
and it really has been many years since I looked at sendmail. hic ;-0

Oh, dont forget to restart sendmail
