Hi everyone

and happy new year!

I am in contract with a webhoster, having webserver, email and a few other things.

But, there is no way to backup my emails stored on their imap server.
Meaning, when anything happens to that infrastructure (or they go broke)
then all my emails are gone.

So, I'd like to mirror them via imapsync to a local instance of some imap server, and then pack them together as a tgz archive.

Now I see, that there are several solutions out, see subject, and I don't
know which one fits best and what component is needed.

Does anyone have some experience here? Do I need an mta (exim for
instance) to just sync emails from external imap server to local?

Thanks for any hint!

Best regards,

Markus

I use POP3 for fetching mail from the public-facing server onto my own
machine. So the only mail store that needs backing up is already under
my control.

Dovecot is fairly easy to set up. IrCOve not tried the other IMAP servers.

IrCOve never used imapsync but thererCOs no reason copying messages from one IMAP server to another should require an MTA.

Personally I'd ignore all those "solutions" as overkill and use
movemail from GNU Mailutils:

movemail -v imaps://no_reply@dipl-ing-kessler.de mh:///home/[user]/Mail

If you have special characters like '@' in the username, you
may need to percent-encode them, eg. "%40".

https://www.mailutils.org/wiki/Fetching_Mail_with_Movemail

I use MH format for storing the mail, check what format/s your
email client understands and change "mh://" to suit.

https://www.mailutils.org/manual/html_node/Local-Mailboxes.html

I actually use POP to get mail using movemail myself, but it works
with IMAP too.

It saves the mail as text files. The metadata information (folder

Hi Kev,

movemail seems to work, thanks!

Well, in the document mh was misspelled as
'mh://Mail' instead of
'mh:///Mail', so it took a while until I got it to work.

Anyway, is there an option to automatically transmit content of more than
1 folder, i.e. inbox, draft and sent... at once?

Best regards,
Markus

What is this "mh:" in a URL? Never saw that before. Is that part of

I think you have to run a separate movemail command for each
folder (and pointing to each destination folder). But you could put
them in a script and have it add the password or set it in
~/.mu-tickets so you don't have to enter it manually multiple
times.

No, just add the folder to the URL, such as:

movemail imaps://foo@example.com/draft mh:///tmp/Mail/draft

I just tested that and it works for me. I can't see any way to
download all the folders with one command like you asked before
though.

By the way, if you want to keep the messages on the server, you
probably want to use the "--sync=uidnext" option:

Maybe, but it might also get you blocked for too many connections

As explained at the link, adding "--sync=uidnext" avoids
re-downloading old messages that have already been retrieved when
you run it again.

B.t.w., just trying to download folders with special characters in them, like "Entwurfe" (drafts). I did not make it yet to get this encoded (for instance "u" in html: &uuml;)

With percent encoding that character turns into "%FC", or "%C3%BC"
if it uses UTF-8. There's a conversion table here:

Yes, debian has it and openSuSE has it.
And I can confirm that compiling from scratch is not as easy as it looked like. I tried to create a package for Mageia, based on the original
tarball, but there are plenty of dependencies not visible during configure/make/makeinstall. It compiled and built, but the result was not funtional. Creating a new rpm out of that failed as well.

Trying to "swipe" the source rpm from other distros is also far from
trivial because most of them are based on tarball 3.15 ... 3.17, which is
6 years or older. So, the current version 3.21 makes some patches obsolete
and instead new dependencies are to be expected.

First I also thought of this text-based set of tools as being an easy job
to build a package, but it turned out that this is not the case.

Best reagards,

Markus

On Debian and derivatives, if you want to build your own version of a
package, a quick rCLapt-get build-dep -2package-+rCY will get you all of the dependencies for the standard version of that package. Which should be
most, if not all, of what you need.

And what's with this reluctance to compile from source, anyway? It's
part of the bread and butter of running any Linux distro.

Yes, debian has it and openSuSE has it.
And I can confirm that compiling from scratch is not as easy as it looked like. I tried to create a package for Mageia, based on the original
tarball, but there are plenty of dependencies not visible during configure/make/makeinstall. It compiled and built, but the result was not funtional. Creating a new rpm out of that failed as well.

Well I built GNU Mailutils 3.21 from source with all the
functionality you require and noted the following dependencies:

readline-dev, libunistring-dev, gnutls38-dev, tcp_wrappers-dev,
libltdl, libtool-dev, libgsasl-dev

At least libgsasl-dev probably isn't needed for your use since I
only added that to enable SMTP authentication using putmail. IMAP authentication using movemail was working before that. Some others
might be surplus to requirements too.

It _does_ tell you better than some what dependencies it's using,
although I agree the docs aren't so clear about the old "what does
this dependency do for _me_?" problem, which is hardly unique to
this project.

Interesting, thank you!

Well, these are the BUILD dependencies - are there RUNTIME requirements
also?

I use Cyrus and like it.
It saves the mail as text files. The metadata information (folder permissions, read status etc.) is saved in local databases.

"local databases" - is this mysql or text based databases?

B.t.w.: Saving emails as text files lets me hope that after upgrade of the imap service or even OS upgrade one day, the old backups stay usable?

I am asking this because I once got into big trouble when I had to move multiple mysql databases to a new machine with new OS and new version of mysqld. - Nothing worked and I had to use mysql-dump to export the data as text-dump on the old system and import them into the new one.
After that, the permission system also had to be set up from scratch
because of different data format...

Using the dump format is how yourCOre supposed to do it. Been there,
done that, had to download and run an old MySQL binary to go back and
do the dump the proper way (thankfully old binaries are available for
just such a purpose).

mysqldump lets you include table permissions with the rCL--system=usersrCY option.

Generally (but I don't promise that it always works) if you have the dev
package installed in order to meet the build requirements you not need anything more at runtime.

There are non-dev packages that meet *only* the runtime requirements for people who don't need to meet the build requirements, but if you have
the dev packages you don't need those as well.

B.t.w.,

how do you install all the files retrieved from compiling the tarball from scratch, if you want to avoid building a deb or rpm?

Meaning, do you let "make install" write directly to the filesystem, or do
you pack all that files in one tar.gz and then use "alien" to transform it into a deb or rpm?

Markus

ThatrCOs usually how itrCOs done. All the well-behaved build scripts
default to putting things in /usr/local, where they donrCOt clobber
stuff handled by your system standard package manager.

Sure, all of those with "-dev" removed, except libtool. You can
probably use whatever version of the gnutls package for your distro
is the latest.

readline, libunistring, gnutls, tcp_wrappers, libltdl, libgsasl

Although you can build it without some of those, such as libgsasl
as mentioned before. Of course exact package names will differ
between distros, especially with the "lib" prefixes.

"ldd `which movemail`" is a quick way to see all the libraries
used by the executable, however it will show additional libraries
used by the direct dependenies, without distinction. Another way
is using "readelf -d `which movemail` | grep NEEDED", which just
gives you the immediate dependencies, but then in this case you
get a bunch of "libmu_*" Mailutils libraries which then also need
to be checked with "ldd" or "readelf", and that gets confusing.
Also those tools won't show any libraries or executables that are
loaded after the program has started. Then you have to work out
which packages the libraries belong to, for which the method is
specific to your distro or package format.

Anyway in this case you can just go from the list I gave you above.

If you want to install to the system then of course "make install",
if you want to make a package or just a tar file that can be
unpacked to "/" on similar systems, DESTDIR is useful:

sudo make DESTDIR=/tmp/mailutils install-strip

That installs everything into equivalent directories under
/tmp/mailutils as when you do a "make install", with debugging info
stripped to avoid wasting space. You should still run it as root so
that the file permissions are set correctly. Then you can make a
package or tar archive from the contents of that directory for
installing to other systems running the same distro.

Note occasionally programs won't support "DESTDIR" and will then
install to "/" anyway, and also some won't understand
"install-strip" so you must use "install" instead, then run "strip"
on the binaries manually. But Mailutils supports both, as, it
seems, do all GNU projects.
