\r
62 It would be missed. I have set the timespan to look backwards for new
\r
63 mail to one month to be a bit safer against the stuck-in-queue cases,
\r
64 but mails with older Date: headers would definitely get missed.

\r
73 Is that even possible? I thought that notmuch guarantees the uniqueness
\r
74 of indexed message ids. The only reference I could find without trying
\r
75 to read the code was this thread id:87mwyz3s9d.fsf@star.eba from 2012,
\r
76 which supports the assumption.

\r
89 I have one laptop and one desktop and switch between them almost daily,
\r
90 and run a hibernate script that does notmuch dump + git push, and a
\r
91 resume script that does git pull + notmuch restore. For hibernate /
\r
92 resume the speed of those operations is acceptable, but I wouldn't want
\r
93 to incur that wait for every time checking for new mail.
\r
95 Here is how long they take (on a machine with an SSD, which certainly
