Here is an example:

  results = match(myaccount, 'INBOX', myfilter)
  headers = fetchheaders(myaccount, 'INBOX', { 'from' }, results)

  for msgid, msghdrs in pairs(headers) do
	  -- check for "From: foo at bar"
	  _, _, user, domain = string.find(msghdrs, 'From: ([%w.-]+)@([%w.-]+)')
	  if (user ~= nil or domain ~= nil) then
		  print(msgid, user, domain)
		  -- move(myaccount, 'INBOX', myaccount, user, { msgid })
	  end
	  -- check for "From: Foo Bar <foo at bar>"
	  _, _, user, domain = string.find(msghdrs, 'From: .+<([%w.-]+)@([%w.-]+)>')
	  if (user ~= nil or domain ~= nil) then
		  print(msgid, user, domain)
		  -- move(myaccount, 'INBOX', myaccount, user, { msgid })
	  end
  end

Basically, it fetches the "From" headers of the messages that match the filter,
tries to find the user and domain of the message and then moves the messages to
a mailbox named after the user (actually it just prints the user and domain,
for testing purposes).
