[Dovecot] Panic: IMAP: Trying to allocate 2273345672 bytes

[Mark Zealey]

I've just found another user that has the exact same error message (same
number of bytes). However, this error only happened once, the user has
logged in successfully since then and there was not an error about the
uidlist having duplicate entries.

Thanks,

Mark
