commit 165c0fcd811c4f1766ff90c04f2b00ca10be9ab0 Author: David Fifield <david@bamsoftware.com> Date: Wed Oct 3 11:48:57 2012 -0700 Delete Gmail messages from Trash to really delete them. After being deleted from INBOX, messages were being "archived" in All Mail. We can delete them for good by copying them to Trash and then deleting them. https://support.google.com/mail/bin/answer.py?answer=78755 http://gmailblog.blogspot.com/2008/10/new-in-labs-advanced-imap-controls.htm... --- facilitator/facilitator-email-poller | 33 ++++++++++++++++++++++++++++----- 1 files changed, 28 insertions(+), 5 deletions(-) diff --git a/facilitator/facilitator-email-poller b/facilitator/facilitator-email-poller index 3f5c4d8..412b5eb 100755 --- a/facilitator/facilitator-email-poller +++ b/facilitator/facilitator-email-poller @@ -239,14 +239,32 @@ def handle_message(msg): log(u"registering %s" % safe_str(fac.format_addr(client_addr))) fac.put_reg(FACILITATOR_ADDR, client_addr) +def imap_empty_trash(imap): + typ, data = imap.select("[Gmail]/Trash") + imap.store("1:*", "+FLAGS", "\\Deleted") + imap.expunge() + +# Gmail's IMAP folders are funny: they are not real folders, but actually views +# of messages having a particular label.
