+Hi John,\r
+\r
+Welcome to notmuch, and I'm so sorry to hear that your initial attempt\r
+to use it was so frustrating.\r
+\r
+I'm not aware of any bugs in notmuch that can result in a corrupt Xapian\r
+database. In fact, this can't be a bug in notmuch alone (since Xapian is\r
+detecting the corruption). There must at least be a bug in Xapian or\r
+else some lower-level failure is occurring (disk full?) that Xapian\r
+can't deal with.\r
+\r
+I've not yet encountered a corrupt Xapian database, so I'm afraid I\r
+don't have any tips to help you with that.\r
+\r
+But I'm also surprised to hear that it takes you days to incorporate\r
+your mail into a notmuch database. I have over 600 thousand messages\r
+myself, and it takes a few hours (maybe 4?) to incorporate all of these\r
+messages, but not days, (also with an Intel SSD).\r
+\r
+So there's some performance problem that you're having in addition to\r
+the database corruption. Hopefully we can figure that out. What kernel\r
+and filesystem are you using? Are you using an encrypted partition?\r
