Alternative SMTP Server

Send Feedback

When you access your own ISP e-mail through a different network, for example through a mobile operator, the ISP may refuse to allow sending mail by using SMTP. It is fairly common to prevent spam abuse by allowing only clients that are authenticated on the ISP network to send mail.

To resolve this problem, you can set up your own SMTP server for your users. Setting up your own SMTP server requires alternate credentials. Windows Mobile™ software enables separate credentials to be used for Outgoing (SMTP) mail server authentication, either through the E-mail Setup Wizard (Messaging Application Inbox > Menu > Tools > Options), or by using the EMAIL2 Configuration Service Provider. Previously, only a single set of credentials could be used for both incoming and outgoing servers.

The following table shows the EMAIL2 CSP settings for the alternate outgoing e-mail account.
