Connection Errors

Many connection errors include a number. See the Number Error Page for help with these errors.

Send & Receive Basics:

Send & Receive problems can be complex to solve, but generally these solutions apply:

  1. If you can receive but not send then you have a bad SMTP configuration
  2. If you can send but not receive you have a bad POP or IMAP configuration
  3. Solutions:
    1. You can try re-entering info.
    2. You can delete account and create a new one.
    3. Using copy/paste can result in an extra space being added. Type carefully.
    4. Check your Keychain for corruption.
    5. Turn off the Firewall
    6. Run a permissions fix on the hard drive and home Library folder
    7. Create a new location in System Preferences --> Network
    8. Be sure you have updated port setting for new security updates. Contact your ISP for changes.

Turn off the Firewall

It is possible this problem could be due to firewall conflicts with MobileMe or other connection issues. Turning off the Firewall could enable proper SMTP connections again. To turn off the Firewall, go to the "Security" system preferences and select the "Firewall" tab. Then select the "Allow all incoming connections" option and retry send & receive. Turn it back on after testing!

Run a permissions fix on the hard drive and home Library folder

Some users have found that their problems were from inaccessibility due to permissions problems in their home directories. To ensure accessibility for files, first run Repair Permissions on the main hard drive, and then check send & receive.

If this fails,, run ensure the account has read and write access to all the files in the user library. To do this, run the following commands in the terminal (enter an administrator password when prompted):

  • sudo chown -R `id -un` ~/Library
  • sudo chmod -R u+rw ~/Library

The first command will recursively change the ownership and group of all files in the library folder to that of the current username and groupname of the active user; the second will ensure the owner of the files has both read and write permissions on all files in the library. When these commands have been run, open Entourage and test.
