WiscMail - Configure SMTP Authentication To Use Port 587

Some Internet service providers have blocked access to SMTP port 25 for sending mail. These ISP users will receive errors when they try to send mail with an email client configured to use SMTP Authentication on port 25. Some users will be able to send mail by by configuring their email client to send mail on port 587 instead.

Disclaimer: This configuration is not guaranteed to work for all users. If you configure your client using the instructions below and continue to have sending problems, please view WiscMail - Cannot Send Mail From Off-Campus Networks.

Use the documents referenced below to configure your e-mail client but make the change specified.
