Trying to retrieve emails using LIKE query with MailBox (imap_tools module)

Question

I would like to retrieve all "from" emails that begin with an "a" from my gmail account.

Here is what I currently have:

with MailBox('imap.gmail.com').login('blabla@gmail.com', 'blabla') as mailbox:
    froms = [msg.from_ for msg in mailbox.fetch()]

The problem is I can't find anything in documentation referring to a LIKE query. I tried this:

froms = [msg.from_ for msg in mailbox.fetch(AND(from_="a%"))]

but it doesn't work.

Answer 1

This is impossible.
