Troubleshooting Mail issues in Mac OS X 10.6 Snow Leopard
Various reports have surfaced around the Web regarding unexpected behavior of Apple's Mail application in Mac OS X 10.6 Snow Leopard, prompting Apple to release a knowledge base article describing possible troubleshooting steps for the program.
MacFixIt reader "Gerald S." reports:
"After upgrading to Snow Leopard, I can no longer send mail. I have a clue, though. The issue seems to be related to existing mail accounts. If I create a new mail account, it works just fine. Now we need to figure out how to import older mail into a new account."
If you are having issues sending Mail in Snow Leopard, you may need to update your authentication settings for your outgoing mail.
Users should follow Apple's Mail Setup Assistant or contact their ISP to determine the proper settings for their e-mail service.For more on troubleshooting Mail in Snow Leopard, read the entire Apple KB Article.After obtaining the proper settings for your mail account, Apple suggests these steps:
- From the Mail menu, choose Preferences.
- Click Accounts, then select the account that is having issues sending messages.
- From the SMTP server pop-up menu (at the bottom of the window), choose "Edit SMTP Server List".
- Click Advanced.
- Select the 'Authentication' pull down menu and select the appropriate authentication type (from your ISP or the Mail Online Setup Assistant).
- If necessary, fill in the username and password.
- Click OK

Address book in Mail still does not reflect the Address Book application accurately. The sort order does not work and "No Name" appears in addresses that are filed under Company Name (Company Name is omitted in this view from Mail). Very very buggy stuff. What a feasco.
I've never had this kind of problem with any upgrade from Apple before. it's unacceptable by any standard (except perhaps, Windows). I expect Apple to be above releasing such buggy, almost Beta, software . . . and then to actually CHARGE me for it! Not good. Not good at all. After reinstalling the separate Aps from the Snow Leopard disk, most of the problem were resolved. However, the address book is still buggy and mail occasionally crashes for no apparent reason, randomly. I'm very disappointed in this "upgrade".
1. Copying an address used to copy just the email address. Now it copies the whole name in the form "FirstName LastName <email@address>" . This makes it virtually impossible to copy email lists anymore. Who thought this was an improvement?
2. Mail can't seem to handle changing font typefaces when it would switch from one font to another (e.g., regular to italic, or regular to bold, or regular to bold italic). Switching from regular to underline isn't a problem, perhaps because it isn't a typeface switch?
I solved the display problems by deleting all things related with the bundles deactivated by SL in my pref plist of Mail.
For authentications problems, I added the port 25 in my smtp settings.
Where is this sorry?
Non of the view available net support solutions did work.
Including failure of apple trouble shooter site for 10.6 mail problems!!!
I think IŽll buy a window thing, then I know iŽll be in for trouble anyway.
My accounts info would not remember the passwords for each account and keychain kept reporting an error in accessing the keychain.
Deleting the keychain "session" (links and files) and restarting (forces OSX to recreate a new session keychain). Add to put in the accounts passwords again and then everything went back to normal.
Of course deleting the session keychain means that I will be asked to confirm access to the keychain at least once everytime something wants to access the keychain for the first time but that is a small price to pay. Maybe better solutions are around but that worked for me and may be helpfull to someone else
1)Beach Balls everywhere - almost every time I click between inbox and other mailboxes, I get a beach ball for as long as a minute
2) Occasionally the message count at the top of the window is way off, for ex. - "INBOX(189,210) and I have only 450 messages in that box. I tried creating a new mail box, and moving the 450 messages from the INBOX to the new mailbox, and the message count was correct. I then moved the messages back and the problem was resolved - EXCEPT - it returned. It is a problem that only occurs occasionally.
3)AND THE MOST ANNOYING, EVEN MORE ANNOYING THAN THE LINGERING BEACH BALLS IS - Mail won't quit. It occasionally does after a long time, but it almost never quits.
I have rebuilt the database by dragging "Envelope Index" and the folder RSS from ~Users/XXX/Library/Mail/ to the trash and restarted Mail. This imported the mail messages and the problems got slightly better.
I switched the Check Mail option to check mail manually.
I turned off Time Machine.
I ran Disc Utility to repair disk and repair permissions.
I only have two accounts turned on, my me.com account and my main email provided by my cable company.
I deleted all messages off the servers.
I tried turning each account off to see if it was the problem, no change.
Any ideas.......... anybody???
On the lead screen you get when you put the Snow Leopard disk in, go to Optional installs >> Optional Installs.mpkg. After the regular license agreement, and selecting the install drive, under the Applications you will find all standard OS X applications, including Mail.
The issues are just surfacing on my Mail application. Can send mail to some addresses, not to others. Sometimes I can download messages, as time goes on, more often, not.

BTW: Same thing happens with Address Book

Anyone else? I have noticed that saving attachments is instantaneous - when it works. In 10.5 it took 1 second per attachment to save.
I like Snow Leopard but I seem to have a few kinks...
I solved my problem half I have a brand new account with my provider now sending out messages as well.
BUT VER SLOW REACTING not at all as it was in 10.5 SL appears to stand for SLOW LEOPARD
an UUE ( Unbelievable Unacceptable Error) pay money to test a program!!!!
thanks for you info

I could receive mail but not send same.
Look under Mail. Go to Preferences.Look into Account Information under Accounts.
The Outgoing Mail Server (SMTP) drop-down bar MUST be set to NONE. This will automatically default to the right ISP setting if you have filled in the previous account information.
Then check the box that reads "Use only this server"
Bob's your uncle.
The very second I did this, all messages in my outbox were sent one by one.
