I realize this is not a "supported" support option, but there does seem to be a dearth of "experts" here, as opposed to what I have seen at other companies' forum sites.MBP 2.4GHz, 6GB RAM, 320GB HD, Mac OS X (10.6.5)
Currently Being ModeratedNov 24, 2010 6:03 AM (in response to cgtyoder)This is a very good question. Actually, I don't even know how to associate a digital certificate to an mail account!!!
Does anyone knows where I can find information about this? The Mail help doesn't help!!!MacBook Pro 15", Mac OS X (10.6.5), 4G Ram, HD 160G

I know this thread is old, but I think I have sorted the answer by trial and error and I came across this while researching exactly the same question. I'm using OS X 10.8 Mountain Lion.
Although OS X / Mail automatically chooses the certificate, the preference can be set in Keychain Access. In your email certificate list, right click and then select 'New Identity Preference'. Type in the email address you wish to amend and then select your choice of certificate from the drop down list.
Doing this sorted my problem, since I was seeing errors due to Mail selecting the wrong email certificate.
As an aside, it is easier and more obvious if you are trying to do the same thing on an iOS device. The account details for each email account will show you which certificate is being used and allow you to select your preference.
