Retrieving email securely from Gmail using POP SSL
The free Google email service Gmail offers over 2GB of storage space prompting many people to signup for accounts. In order to access your account you must however use a secure POP connection using SSL.
The purpose of this article is to demonstrate how to connect to a Gmail account using the Java com.jscape.inet.popssl.PopSsl class found in Secure iNet Factory.
The procedures in this article may also apply to other POP servers which provide secure SSL/TLS access.
For a tutorial on sending email using Gmail see Sending email securely using Gmail and SMTP SSL.
- A Gmail account. As of this writing this service is still in beta. If you do not have an account you must get invited to open an account from someone who already has one.
- JDK 1.2.2 or above and Secure iNet Factory
Note
If using a JDK prior to JDK 1.4 then you must download and install the JSSE (Java Secure Socket Extensions). Instructions for doing this are provided in the Secure iNet Factory User Guide.
