------------
The following verbs can be used on a readable mail-recipient/player to search for messages with fields matching a given pattern.
from_msg_seq (objectid or list [,mask])
=> message sequence: messages from (one of) the given objectid(s)
%from_msg_seq (string or list [,mask])
=> message sequence: messages with (one of) the given string(s)
in the From: line
to_msg_seq (objectid or list [,mask])
=> message sequence: messages to (one of) the given objectid(s)
%to_msg_seq (string or list [,mask])
=> message sequence: messages with (one of) the given string(s)
in the To: line
subject_msg_seq (string [,mask])
=> message sequence: messages with given string occurring in Subject:
body_msg_seq (string [,mask])
=> message sequence: messages with given string occurring in body of message
In all cases `mask' is a message sequence which one may supply to limit the range of the search. One way of looking at it is that the message sequence to be returned is first intersected with mask.
