Fix the “Wrong Server” Problem
Each email account you've set up includes settings for a single SMTP server (except Exchange
accounts, which use the same server for incoming and outgoing mail). If you have lots of
accounts, Mail may have settings for lots of SMTP servers—including, perhaps, some that
are outdated or broken. As a result, it's easy to inadvertently select the wrong SMTP server.
Here's how to make sure that doesn't happen.
Clean Out Your SMTP Server List
First, get rid of any SMTP servers that aren't being used. To do this:
1. Go to Mail > Preferences > Accounts, select any account in the list on the left,
and click Account Information.
2. From the Outgoing Mail Server (SMTP) pop-up menu at the bottom, choose Edit
SMTP Server List.
3. In the list at the top, note the third column, In Use By Account. If this column
is blank for any item in the list, select that item and click the minus button
to remove it (confirming the deletion if prompted to do so). Repeat this step for
every server not in use.
4. Click OK.
Associate the Right Server with Each Account
Next, make sure every (incoming) email account uses the correct outgoing server. Follow
these steps:
1. Go to Mail > Preferences > Accounts, select the first account in the list on the
left, and click Account Information.
2. In the Outgoing Mail Server (SMTP) pop-up menu near the bottom, verify that
the server selected is the one matching your incoming account. If the server ap-
pears to be correct but you're still getting errors when sending mail, proceed
with…
