Hi all.
In prearation for a forthcoming update from Fedora 12 to Fedora 14 I
have saved my Seamonkey profile. While doing this I looked at a mail
folder and was shown an e-mail from Sept 2009. To my surprise it does
not show when I look for it in the usual way with Seamonkey. As far as I
can see only the first item in the mail folder is shown although there
are lots more some of which show in Seamonkey as being before the date
on this item. Cn anyone explain why this happens?

Most "files" in the Mail folder of your profile are mailbox files, each
of them corresponds to one the "folders" which you see in the mail client.
Each of these mailbox files contains emails one after another: if you
look at one such mailbox with a plain text editor such as Vim, Notepad,
etc., you'll see for each message the following:
- one line starting with "From -" with no colon after From
- the email headers, with no intervening empty line. Lines beginning
with whitespace (i.e. with spaces or tabs) are continuation lines.
- one empty line
- the body text, which is what you normally see when reading the email.
This body text may either be one message in plaintext, or it may be made
of several parts (HTML text, plaintext, attachment 1, attachment 2,
etc.) in MIME format. In the latter case there are delimiter lines
between each part, and the same delimiter with two dashes appended marks
the end of the last part, see
http://en.wikipedia.org/wiki/MIME#Multipart_messages
When you delete a message, it is not immediately removed from the
mailbox; rather, for efficiency's sake, it is "marked as deleted" and
nothing else is done to it. Anything marked as deleted in this way won't
be shown by the mailer. It's only when you "compact" that folder (or
when SeaMonkey does it on its own, depending on your Preferences) that
all such messages "marked as deleted" will be actually removed.
If you point your browser to a copy of a mailbox file, it may perhaps
see only the first message, thinking that this file is one message which
you've "saved" as a file in EML format (MIME type message/rfc822) as
when you use the "File → Save As → File..." menu. This would explain
what you're seeing. But unlike what goes before, what I'm saying in this
paragraph is only a guess.
Best regards,
Tony.
