Securing SMTP with SSL

Current Configuration:
I am currently using Sendmail and OpenWeb mail. Both seem to work flawlessly. I am using SSL to retreive mail imap-s port 993. I want to secure outgoing mail using ssl. Security on my system appears tight, I get daily attempts by spammers to relay mail, but so far, so good I hope. I am pretty sure I need to open port 495 with IP tables. I am using Red Hat Advanced Server. Is there lines in the sendmail.mc and use m4 for the sendmail.cf? Do I need to specify this port in /etc/services file? What else needs to be configured?

Thanks
Christyjo

Hi:
I checked my sendmail.mc and none of the above files are listed. The only statement that is close is:
confPRIVACY_FLAGS
I have read the articles, and will digest them and try the suggested changes.
I will respond back

yep because this modifications are in /etc/mail/sendmail.cf not in the mc file. :)
