Capability Option

From MsgServerDocWiki

Updated in release: 7 Update 1

Capability replacement string. The MMP will use the string you specify for Capability instead of its default (own) capability to tell IMAP clients what it (or the servers behind it) can do. This variable has no effect in POP3. There is no need to include STARTTLS and AUTH= extensions as they are added automatically based on the other relevant MMP configuration settings.

There is no need to adjust this string if the backend IMAP servers are entirely Sun servers from the same version of the messaging server installer. Otherwise, it is important to specify a capability list that includes only the features supported by all the backend IMAP servers. The appropriate string can be determined by telnetting to port 143 on each kind of backend server and entering the command c capability. Then list only the capabilities present on all backend IMAP servers.

The EhloKeywords option provides a roughly-equivalent function for the SMTP Submit proxy.
