redownloaded many gigs of mail

[Sandra Snan]

hey again

some cert or something changed, I dunno and it redownloaded a million
email and it took 4 gigs and it took around two days for notmuch to
index it all

how can I prevent this in the future? also I don't like that the emails are
permanently in the inbox on the server. I want them to be safe, sure,
but they don't have to be in the inbox.

I guess I don't really understand how offlineimap works
