I was having this issue too.
I am on Cablevision's Optimum Online (now with Boost, because I run an Exchange Server too.)
The issue with my iPhoto (using my .mac account for iPhoto) not sending was that the outgoing server was not set to use Optimum's outgoing server. I changed it to my optimum user name, port 587, entered my password and unchecked SSL.
I could use port 25 and my exchange server, but decided not to setup a receive connector to relay. The above is just easier.
The iPhoto accounts pane does not import the settings from Mail.app. Please verify that the settings are the same with your Mail.app account as they are with the iPhoto one, don't rely on iPhoto to have it exactly the same.

NOTE: This only applies to those using an iCloud email account that was converted from Mobile Me.
I kept getting errors about not being able to send an email from within iPhoto. After trial and error I fixed by deleting both the email account and the MobileMe account. You'll get some message about it removing albums from your iPhoto (this is okay because they will still be on MobileMe as long as it is active). Then set up your iCloud email account first. Test sending a message. Then set your MobileMe account back up. This worked for me. Note.. MobileMe account is only needed if you still have a photo gallery set up in MobileMe.

I opened iPhoto preferences and deleted the already configured "MobileMe" account. I then clicked the plus "+" symbol/button to add an account and added my iCloud account information. Everything works now. My guess is that this may have something to do with legacy settings after the MobileMe shutdown last month.

This worked for me;
Delete your e-mail accout in iPhoto (settings, accounts)
Add your iCloud account in iPhoto, using your e-mail adress (mac) and password, at username remove @xxx.xxxx
Leave everything else as it is. Restart iPhoto and y're good to go!

This worked for me. Thank you wtobiasjr!!
In addition, I had to change the port to matching the one in the Mail application (for me it was 993). I tried to get this to work like a million times, before I tried restarting the iPhoto app. Finally it worked!
So I recommend if you are using a Gmail account, make sure you've followed these steps.
1. What wtobiasjr described about generating a temp password to grant iPhoto access to Gmail.
2. Change "Port" in iPhoto>Preferences>Accounts>Gmail>Port to what you have in your Mail app.
3. Restart iphoto
4. Send out test photo email from iPhoto.
And hopefully that should work!
