By default, POP3 service and IMAP4 service are not enabled.
To enable the POP3 service of the IMAP4 service:
In the GroupWise Administration Console, browse to and click the GWIA.
Click the POP3/IMAP4 tab.
To enable POP3, fill in the following fields:
Enable POP3 Service: Allow POP3 downloads from a GroupWise mailbox. It corresponds with the GWIA’s --pop3 switch.
Number of Threads for POP3 Connections: The POP3 threads setting lets you specify the number of connections for POP3 download requests. The default is 10 threads. This setting corresponds with the GWIA’s --pt switch.
Number of Threads for POP3 SSL Connections: Specify the maximum number of threads you want the GWIA to use for secure POP3 connections. This setting corresponds with the GWIA’s ‑‑sslpt switch.
Enable Intruder Detection: Configure the GWIA to log POP3 email clients in through the POA so that the POA’s intruder detection can take effect, if it has been configured in the GroupWise Administration Console (Post Office object > Client Settings > Enable Intruder Detection). This setting corresponds with the GWIA’s ‑‑popintruderdetect switch.
Do Not Publish GroupWise Information on an Initial POP3 Connection: This option suppresses the GroupWise information that the GWIA typically responds with when contacted by a POP client. It is enabled by default. This setting corresponds with the GWIA’s ‑‑nopopversion switch.
To enable IMAP4, fill in the following fields:
Enable IMAP4 Service: Allow IMAP4 downloads and management of GroupWise messages. It corresponds with the GWIA’s --imap4 switch.
Number of Threads for IMAP4 Connections: The IMAP4 threads setting lets you specify the number of connections for IMAP4 requests. The default is 10 threads. This setting corresponds with the GWIA’s --it switch.
Number of Threads for IMAP4 SSL Connections: Specify the maximum number of threads you want the GWIA to use for secure IMAP4 connections. This setting corresponds with the GWIA’s ‑‑sslit switch.
Maximum Number of Items to Read: Specify in thousands the maximum number of items that you want the GWIA to download at one time. By default, the GWIA downloads 4,000 items at a time. For example, specify 5 to download 5,000 items at a time. The higher the setting, the more memory the GWIA uses to process a single folder. This setting corresponds with the GWIA’s ‑‑imapreadlimit switch. See also the ‑‑imapreadnew switch.
Do Not Publish GroupWise Information on an Initial IMAP4 Connection: This option suppresses the GroupWise information that the GWIA typically responds with when contacted by an IMAP client. It is enabled by default. This setting corresponds with the GWIA’s ‑‑noimapversion switch.
Click Save, and then click Close to return to the main Administration Console window.
The Post Office Agent (POA) can also be configured to support IMAP connections. You could offer IMAP services internally through the POA to provide faster response time for internal users. For more information, see Supporting IMAP Clients. However, IMAP is primarily available on the POA to support several third-party applications that communicate with the POA using IMAP, while the IMAP services provided by the GWIA provide the standard IMAP access used by users across the Internet.
