We will gladly give you custom advice if you'll post the complete error message.
If you know what change you need to make to the server name, you can do so
by going to Tools, Accounts, select that account, Properties, Servers.
See in your post, the "Server" shows as - Jzs. That is not a valid SMTP
server name. You need to set up your account (Tools - Accounts) with the
appropriate server for your ISP or email provider. If you need help with
that, please provide the part of your e-address after the "@" symbol.
