I want to download emails without any processing, without procmail. I'm trying to configure fetchmail like this:mda /bin/sh -c 'cat > INBOX/new/$(date +%s_%N)'But it resulted in a file named yuchao_326621000, but not the expected 1428556930_751589889. I think this is because fetchmail will replace %s with the current user name.So, how do I encode a '%' in the mda option?What I have tried:mda /bin/sh -c 'cat > INBOX/new/$(date +%%s_%N)'mda /bin/sh -c 'cat > INBOX/new/$(date +\%s_\%N)'Both of the above don't work.
Encode literal percent in fetchmail's mda option
fetchmail
