what i am trying to do is search my mailboxes for a specific subject line.
i seem to be having a problem with the "if subject… " line in the repeat loop.
set theMailbox to mailboxes
repeat with eachMessage in theMailbox
if subject of eachMessage is "Hello" then
set myAddress to sender of eachMessage
end if
end repeat
When you ‘set theMailbox to mailboxes’, ‘theMailbox’ contains a list of mailboxes. Your script is looking for messages. You need one repeat loop that works through the mailboxes and another to work through the messages of each mailbox.
