Mac OS X v10.6: Mail.app won’t open, or "You can't use this version of Mail…" alert after installing Security Update 2012-004:
Fellow user Grant Bennet-Alder offers this solution:
Some users have reported this problem if the Mail Application has been moved out of the top-level /Applications folder, or duplicated in another location.
When the Security Update is done, the old version of Mail is disabled.
The solution has been to:
1) make certain Mail is in the /Applications folder
2) There is no other copy anywhere else.
3) Once steps 1 and 2 have been done, Manually download and re-apply the Security Update (2012-004) by hand.
If the Mail.app has been LOST, it can be re-installed by applying the 10.6.8 version 1.1 combo update. But this update is quite large and it is usually not necessary:

Thanks for the info.
I checked and only have 1 copy of Mail.app.
Just reinstalled the latest Security Update. Still getting the message that my login info is incorrect.
Will try the Combo update later.

Just tried setting up my mobileme email on a friends iMac running SL that was updated with the Security Update. Same problem.
