Detailed Description

Find the keyids of the recipients of a message.

Parameters

addrlist	Address List
oppenc_mode	If true, use opportunistic encryption

Return values

ptr	Space-separated string of keys
NULL	At least one of the keys can't be found

If oppenc_mode is true, only keys that can be determined without prompting will be used.
