Configuring IMAP4 and POP3 Services

IMAP4 and POP3 service settings control how users access their stored messages on the server.  You configure IMAP4 and POP3 services by going to Configuration/Services/IMAP and Configuration/Services/POP on the console.


 

The IMAP4 and POP3 screens are almost identical, organizing the different configuration settings into the following 2 categories and tabs:
 

System

General settings for the IMAP4 and POP3 systems.
Enable service at port: Whether you want the service enabled and what port number you want it to listen to (Default is on, with IMAP4 port 143 and POP3 port 110).

Use seperate port for IMAP over SSL (IMAP4 only): Whether you want IMAP4/SSL connections to switch to a seperate port, and the port number you want to use (Default is off, and port number 993).

Allow anonymous login (IMAP4 only): Whether you want to enable anonymous login (Default is off).

Allow password login: Sets user password login with optional encryption (Default is on, minimum cipher length 0).

Maximum network connections per process: The maximum number of client connections per process (Default is 4000 for IMAP4 and 600 for POP3).

Drop client if idle for: Amount of idle time allowed in the client connection before the connection is dropped (Default is 30 minutes for IMAP4 and 10 minutes for POP3).

Maximum number of threads per process: How many threads can run on any single process (Default is 1000).

Number of processes: How many processes you want to spawn for the service (Default is 1).

Service Banner: The message you want the service to send to clients when they first connect.
