52.8 IMAP4 Switches

The following optional startup switches that can be used to configure the Internet Agent’s IMAP4 service:

52.8.1 /imap4

Enables IMAP4 client access to GroupWise mailboxes through the Internet Agent. See Section 46.3.1, Enabling POP3/IMAP4 Services.

Syntax: /imap4

52.8.2 /imapport

By default, the Internet Agent listens for IMAP4 connections on port 143. This switch allows you to change the IMAP4 listen port.

Syntax: /imapport-port_number

Example: /imapport-144

52.8.3 /imapreadlimit

By default, the Internet Agent downloads a maximum of 20,000 items at a time. This switch allows you to specify, in thousands, the maximum number of items you want the Internet Agent to download. For example, specifying 30 indicates 30,000.

Syntax: /imapreadlimit

Example: /imapreadlimit-30

52.8.4 /imapsport

By default, the Internet Agent listens for secure (SSL) IMAP4 connections on port 993. This switch allows you to change the IMAP4 SSL listen port.

Syntax: /imapsport-port_number

Example: /imapsport-994

52.8.5 /imapssl

Disables, enables, or requires secure (SSL) connections between IMAP4 clients and the Internet Agent. See Section 48.4, Securing Internet Agent Connections with SSL.

Syntax: /IMAP4ssl-enabled|disabled|required

Example: /popssl-required

Option

Description

enabled

The IMAP4 client determines whether an SSL connection or non-SSL connection is used. By default, the Internet Agent listens for SSL connections on port 993 and non-SSL connections on port 143. You can use the /imapsport and /imapport switches to change these ports.

required

The Internet Agent forces SSL connections on port 993 and port 143. Non-SSL connections are denied. You can use the /imapsport and /imapport switches to change these ports.

disabled

The Internet Agent listens for connections only on port 143, and the connections are not secure. You can use the /imapport switch to change this port.

52.8.6 /it

Specifies the maximum number of threads to be used for IMAP4 connections. The default number is 10. You are limited only by the memory resources of your server. See Section 46.3.1, Enabling POP3/IMAP4 Services.

Syntax: /it-number_of_threads

Example: /it-15

52.8.7 /sslit

Specify the maximum number of threads you want the Internet Agent to use for secure IMAP4 connections. You are limited only by the memory resources of your server. See Section 46.3.1, Enabling POP3/IMAP4 Services.

Syntax: /sslit-number_of_threads

Example: /sslit-15
