they should not change in any direction nor fixed for messages having
the wrong ones before touch dbmail - my attention goes here more to
signed messages than specific clients

for me reconstruction is anything which would lead to whatever
difference in the message the client receives to the one received by
the MTA
</Nitpicking Mode>
What about store the SHA checksum of messages before they are splitted
and inserted and bail out in the moment POP3 or IMAP are deliver a non
matching one to the client - the SHA1 at receive should not matter in
performance and the verify and bail per config option
the idea is that we may find border cases we never imagine while the
client may not always display things wrong but dbmail could bail
itself also in cases nobody minds
i am against sha checksums, since that would be quite a bit of extra cpu
load. CRC should be fine to detect errors like this.

Not everything is about re-construction! This is about the
wire-protocol: CRLF encoding. Outlook really should treat LF as a
line-ending, but DBMail really must send CRLF
Let me repeat: there is no corruption, and no re-construction issue
here. It's about encoding the data before sending it to the client.
* split and store of messages was and is still fine
There may be some issues with message/digest. The imaptest is still
failing there. Apart from that: no known issues.
