Hi,

I want to be able to read some of my email, downloaded to my desktop machine,
on my laptop, while
off-line.

The current setup is that the desktop machine donwloads emails from several
accounts using
fetchmail, processes it with amavis and spamassassin, and delivers it into
several folders using
procmail.

I would like to copy some of those folders to a laptop in order to read them in
my free time, while
away from home and internet.


I have tried "mailsync".


The 1st problem with this is that read emails on one machine are not marked
read in the other.

Thunderbird keeps indexes (foldername.msf) which are not (AFAIK) synced. Or, if
using (Al)pine, the
marks are kept as some header modification inside the mbox file; but as the
msgids are the same on
both sides, the changes are not synced.

I though of solving this by keeping two folders, one of them for "read" email,
and move there each
email after being read (a bit of a nuisance, but I can do that).

But aparently mailsync doesn't keep good track of this, and replaces the
"deleted" emails in the
laptop with copies from the main machine.

This won't do.

Unless I'm doing things wrong (which I might, the documentation is not very
complete), I can't use
this method.


Yesterday I discovered "offlineimap". The description is very promissing:

Summary : OfflineIMAP - Powerful IMAP/Maildir synchronization and reader
support
Description :
OfflineIMAP is a tool to simplify your e-mail reading. With
OfflineIMAP, you can:

* Read the same mailbox from multiple computers, and have your
changes (deletions, etc.) be automatically reflected on all
computers

* Use various mail clients to read a single mail box

* Read mail while offline (on a laptop) and have all changes
synchronized when you get connected again

* Read IMAP mail with mail readers that do not support IMAP

* Use SSL (secure connections) to read IMAP mail even if your reader
doesn't support SSL

* Synchronize your mail using a completely safe and fault-tolerant
algorithm. (At least I think it is!)

* Customize which mailboxes to synchronize with regular expressions
or lists.

* Synchronize your mail two to four times faster than with other tools
or other mail readers' internal IMAP support.



This morning I read the manual
(/usr/share/doc/packages/offlineimap/manual.html), which appears to
be written for version 4, while the rpm is version 6. It is indeed interesting,
but there is a big
snag, probably unsurmountable in my case: it does the syncing not against the
desktop machine, but
against a common imap server that all the computers use, ie, the ISP imap
server.

This, again, will not do.

What I would, then, need, is an imap server in my desktop machine, but one that
serves the mail
structure under /home/USER/Mail/LotOfmboxFiles as an imap server. Without that
I can not use that
"offlineimap" thing. Perhaps not even then, it could mess the handling by
procmail.



Do you have more ideas I could try? O:-)
