wip-postfix

wip-postfix

[Gábor Boskovits]

Hello Guix,

I've just pushed my work on postfix as a new wip-postfix branch.
There are currently two commits, one for the package and one for the service.

I adjust them in tandem.

Current status:
Service starts fine. Some warnings are sent on startup, telling that
some coreutils stuff is not found. No testing was done as of now.
Feedback welcome.

Best regards,
g_bor

That's great!  Yesterday I finally found some time to look at it.

I fixed that, see attched patch.

I found mail delivery not to work, out of the box (using attached
config).

When I start a vm like so:

    sed -e 's,-append ",-append "console=ttyS0 ,' $(./pre-inst-env guix system vm gnu/system/examples/postfix.tmpl) > rvm.shn
    sh rvm.sh -nographic -m 2G -net nic -net user,hostfwd=tcp::10022-:2222,hostfwd=tcp::10025-:25

it does not work for me; I get

--8<---------------cut here---------------start------------->8---
$ telnet localhost 10025
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 komputilo.localdomain ESMTP Postfix

rcpt to: alice
451 4.3.0 <alice>: Temporary lookup failure
data
data
554 5.5.1 Error: no valid recipients
--8<---------------cut here---------------end--------------->8---

When I hack around and create /etc/ailases.db, it works.

It looks like most everything is installed in a single, flat directory

    /gnu/store/pyv0rpd6zs0m2i482cb8qxd6mhf5b47z-postfix-minimal-3.4.8

executables, copies of readmes, (unused?) config files (main.cf,
aliases)?

Anyhow, this is a great start; next Mailman?

Yes, but can be easily separated. The config files are installer generated,

One thing that blocks me from finishing this is that the setuid programs in
the os declatation should be extended, so that we can use the privilege
separation of postfix. I would like to propose a patch later this week.

Luckily, that was easily fixed by updating postfix to 3.5.0.

I found we already have mail-aliases-service-type, so I used that,
together with running postalias.  Now, queuing mail works ootb...but
delivery seems not to work: it remains queued.

I rebased wip-postfix and added a couple of patches for this.  Please
feel free to revert them if you don't like it :-)

I will have a look early next week. Most probably the setuid stuff is
missing, and access is denied to something.

Nothing in particular. I had little time recently. I just finished a bigger
project, and I was on holiday. I will try to propose an interface for this
next week.
