Unable to send e-mail from iphoto 11

When I tried to send a photo from my newly updated iphoto 11 I got "password not recognized" support at Mac said it was caused by my service provider, as my e-mail works just fine I doubted that. re-entering my password in preferences did not fix the problem, but when I read all the info in preferences I noticed the port number had been changed, missed that one at first. I changed the port no back to the correct one at iphoto works well now. This is a solution posted, not a problem, wondering if anyone else has experienced this?
