Recent days, I have problems sending out email in Mail App, on Mac OS X Mountain Lion. Little invistigation shows that the accounts information for SMTP server are messed, wrong accounts are used for different servers. The solution is simple and straightforward:
- In Mail, open
Accountstap, select the account whose
Outgoing Mail Server(SMTP)is labeled as
- Click the SMTP server, and select
Edit SMTP Server Listfrom the list;
- Then you need to fill in the correct username and password.
