Mail.app unexpectedly quits b/c I tried to email VERY large photo files

Help! I (stupidly) tried to email several large photo files from iPhoto via mail.app. All five of these emails are still sitting in drafts folder.

Now I can't even open mail.app. It immediately quits.

I deleted the drafts in Finder (or at least I think I did) and emptied trash. Still doing same thing.

Here is what Console says at the time I first started having this problem:

6/8/12 5:51:44 PM com.apple.launchd[87] ([0x0-0x14014].com.apple.mail[130]) Exited abnormally: Bus error

6/8/12 5:52:30 PM com.apple.launchd[87] ([0x0-0x1b51b5].com.apple.mail[6622]) Exited abnormally: Bus error

6/8/12 5:57:36 PM com.apple.launchd[1] (0x10a420.mdworker[6504]) Exited abnormally: Bus error

A little farther down the log it says this:
