Thank you for your report.
In turn, thanks for your feedback and support.
I am trying to see how this corruption could happen, and nothing
obvious sticks out.
Is the corruption always at the start of the mailbox? Has it
appeared elsewhere?
Yes, always at the start of the mailbox. Simply replacing the
corrupted beginning with the expected "From " header resolves the
issue and the users report that the rest of their mailbox is fine.
Do the affected users report having done anything with the first
message of the mailbox?
No. In some of the cases, they were trying to do a bulk delete or
move of a lot of email messages to try to clean up and reduce the size
of their inboxes, but the feedback I've gotten suggests that they were
not changing the first message.
Does the first message of the mailbox have an X-IMAPbase: header?
In the first example (which seemed to involve a single line), yes:
X-IMAPbase: 1122482547 17694 $NotJunk $Junk JunkRecorded $Forwarded
...in the second one, which seemed to involve about 8 header lines,
no, although I do see a:
X-Keywords: NotJunk JunkRecorded $NotJunk MessageJunkMailLevel
...header.
In imapd.c, about 10% through the file, there are lines which read:
[ ...patch elided for brevity... ]
Does that make the problem go away?
I will test this and report back. Should I stick with imap-2007 or
try with imap-2007a.DEV...?
