If you handle mass mailing through desktop email clients, you have to set up the incoming mail server (POP) and outgoing mail server (SMTP) correctly before you start sending and receiving emails.

Here 1and1Soft summarize POP and SMTP server settings of all commonly used email services. They are all collected from the official sources (namely, the official websites of Gmail, Hotmail, Yahoo! Mail and AOL Mail, etc.). But your email service provider may change its mail server settings without any prior notification. It is suggested you contact your email service provider in case you encounter any error during the account setup or email delivery process.

In most mass mailing software, you only need to set up the outgoing mail server (SMTP server) address and port number because the software is sending mass emails out only.

In 1and1Mail, you only need to set the SMTP server correctly.
