Hi, I'm trying to experiment with notmuch.
As I understand it, notmuch does not handle mbox for input. The problem is that all my mail is currently in mbox format. So I first tried converting mbox to maildir using mb2md. It didn't do a good job. When I subsequently tried importing to notmuch, notmuch complained about lots of non-mail files - I confirmed that indeed mb2md had botched converting those emails. So then I tried to convert to mh format using Sylpheed. This seemed to go well, but then when importing to notmuch, it complained again for about 20 emails, and a manual check confirmed that some messages did not get converted properly to mh (they don't show up in Sylpheed). And then I noticed another discrepancy. mutt shows that I started with 44473 messages in mbox. When I imported into Sylpheed, it showed 44482 messages (no idea where the extra 9 came from). However, notmuch is reporting that it processed 44482 files, but that it added 35602 messages. Why only 35602 (it complained for only about 20 messages)? A search confirmed that some messages that show up in both mutt (in mbox) and Sylpheed (in mh format) were not indexed. So I want to know: When you guys switched to notmuch, how did you ensure you did not miss any emails. I really, really, really don't want to lose any emails in this process! Thanks.
