Add a method to move messages to IMAPlib #77508

on Apr 21, 2018 mceplmannequinMannequinAuthorI am in the process of writing script working with IMAP first time using Python 3 for it (unfortunately, most of servers where I run other code is so ancient that even Python 2.7 is a stretch), and it is really nice experience so far. Many problems which are dealt with on the StackExchange with arcane workarounds are now resolved in email or imaplib libraries. Thank you, everybody!
However, it seems to me that few higher level commands could greatly improve useability of imaplib library. For example, moving messages (not fault of imaplib) is still horrible mess. In the end I had to write this monstrosity just to make moving messages working:
Capas = collections.namedtuple('Capas', ['MOVE', 'UIDPLUS']) def __login(self, host='localhost', username=None, password=None, ssl=None): self.box = imaplib.IMAP4_SSL(host=host) ok, data = self.box.login(username, password) if ok != 'OK': raise IOError('Cannot login with credentials %s' % str((host, username, password,)))
ok, data = box.capability() capas = data[0].decode() box.features_present = Capas._make(['MOVE' in capas, 'UIDPLUS' in capas])def move_messages(self, target, messages): if self.box.features_present.MOVE: ok, data = self.box.uid('MOVE', '%s %s' % (messages, target)) if ok != 'OK': raise IOError('Cannot move messages to folder %s' % target) elif self.box.features_present.UIDPLUS: ok, data = self.box.uid('COPY', '%s %s' % (messages, target)) if ok != 'OK': raise IOError('Cannot copy messages to folder %s' % target) ok, data = self.box.uid('STORE', r'+FLAGS.SILENT (\DELETED) %s' % messages) if ok != 'OK': raise IOError('Cannot delete messages.') ok, data = self.box.uid('EXPUNGE', messages) if ok != 'OK': raise IOError('Cannot expunge messages.') else: ok, data = self.box.uid('COPY', '%s %s' % (messages, target)) if ok != 'OK': raise IOError('Cannot copy messages to folder %s' % target) ok, data = self.box.uid('STORE', r'+FLAGS.SILENT (\DELETED) %s' % messages) if ok != 'OK': raise IOError('Cannot delete messages.')
It would be nice if some capabilities detection (see bpo-18921) was embedded into login method, and if some version of move_messages was included in imaplib itself.

For some reason, this seems to not play well with <instance>.uid('move',...)
on a cyrus imap server (v2.4.19).

on Jul 3, 2020 mceplmannequinMannequinAuthor- no this has not been included anywhere, just in the unfinished PR on GitHub
- only thing which I was fighting to get into Python (and I did) was https://bugs.python.org/issue33336 but that’s another issue (without this whole discussion here would not be even possible), it is now part of the upstream Python
- are you certain that the IMAP server in question supports MOVE command? (have you noticed all that business with CAPABILITIES and particularly the UID one?)
