Explanation

Hi Paul,

Allow me to ask an explanation:

When running dbmail-util for message cleanup, why do I have :

Repairing DBMAIL physmessage integrity...

Ok. Found [256] unconnected physmessages.

Ok. Orphaned physmessages deleted.

Repairing DBMAIL partlists integrity...

Ok. Found [0] unconnected partlists.

Repairing DBMAIL mimeparts integrity...

Ok. Found [778] unconnected mimeparts.

Ok. Orphaned mimeparts deleted.

256 unit's on one side, and 778 on the other?

Shouldn't the values match? I mean:

Mimeparts = physmessages X 3

Or the reason is, 'cause messages can have one mimepart, or some of them,
never a fixed number, correct right?

Jorge,

a plain/text rfc822 message will consist of two mimeparts, like the good
old messageblks storage.
1: rfc822 headers
2: rfc822 body

a message/rfc822 would result in:

1: rfc822 headers
2: mimepart headers
3: mimepart body

a multipart message with only one mimepart will result in at least 5
mimeparts:
1: rfc822 headers
2: multipart preface
3: mimepart headers
4: mimepart body
5: multipart postface

But then a message/rfc822 mimepart can contain a multipart message which
may contain anything. Full recursion.

So there number of mimeparts (M) related to the number of physmessages
(P) is something like:

M = A . P
2 <= A < inf
