I have Mail 4.5 on my new Mac. I can receive emails, but cant send emails. What is the proper way to set it up? My internet service provider is of no help.

    First of all you have to find out what settings your Email provider requires you to set.
    - SMTP Port (e.g. 25, 465, 587...)
    - SSL required/supported?
    - SMTP auth required? (usually it's either MD5 or plain/password)
    - your Username and Password

    Then in Mail go into Preferences > Accounts and at the very bottom there is the option to edit SMTP Settings:
    1. select your SMTP Server (
    2. click on Advanced
    3. input the correct settings
    4. when you are done click OK and close the Preferences
    I recommend to actually quit Apple Mail (cmd + Q) before trying to send emails with the new settings.

    Two important things:
    New SMTP settings are not applied to Emails in your outgoing folder! You either have to move them to Drafts and resend or delete them.
    Outgoing mails are processed in a linear fashion. This means if one email is stuck for whatever reason all subsequent emails will be too.

    check your "Connection Security" setting; it should be either "STARTTLS" or "None". If set to "SSL/TLS", you'll get the timeout. You should also ensure that your SMTP server is set to ""
