Automatic upgrade to mail2

[davidep (Davide Principi)]

Since NethServer 7.5 was released new installations of the Mail module are based on mail2 packages, and run Rspamd as spam filter. Existing installations based on amavisd-new can be upgraded manually, as announced here:

• Email 2 (Beta) released
• http://docs.nethserver.org/en/v7/release_notes.html#major-changes-on-2018-06-11

I think the new Mail module is stable enough to fully replace the older one in an automatic way. I propose to release an automatic upgrade to the Rspamd based implementation.

Maintaining two different implementations that do the same thing is a waste of energy!

What do you think?

What do you think?

It sounds like a good idea. What are the risks? Have we seen unintended or unexpected operation as a result of the manual upgrades?

[mrmarkuz (Markus Neuberger)]

I agree, all my servers are upgraded already.
Only issue may be with raspberry arm implementation as it seems not easy to use mail2 because of RAM usage (clamav), see https://github.com/markVnl/nethserver-arm-dev/issues/12

Only issue may be with raspberry

With Raspberry I guess the best thing to do is to avoid mail-filter completely: too much RAM required!

Not here

Work has been done and it is possible to install nethserver-mail2 without the nethserver-mail2-filter package (e.g. make it optional) . Did no work / testing on arm though and the repo still needs to be updated.

[mark_nl (Mark Verlinde)]

One minor topic i’d like to point out is the nethserver-mail-smarthost dependency.

Mail missing from configuration menu after uninstall / re-install

that would make sense when i removeed nethserver-mail-* would have taken smarthost out, and I didn’t re-install it. should that perhaps be a dependency of mail when installing? or did I not read enough in the docs? I don’t mind getting told to RTFM at all.

If there are issues in a corner-case and you start to thinker to correct it; you might remove smarthost accidentally.

[davidep (Davide Principi)]

Once we merge smarthost code into nethserver-mail repo we can fix the dependency too

Updated arm repositories, made the filter-package optional and so far so good!

[mark_nl (Mark Verlinde)]

Curious about the Status because while testing / working on other stuff came across a unpleasant side effect of the comps solution to pull the latest nethserver-mail stack in;

If a group containing nethserver-mail2 is removed it removes the mail2 packages and packages depending on mail2 too.
To reproduce:
Install from software center Email , Roundcube web mail and WebTop 5 groupware (or sogo).
then remove Roundcube web mail.
or shortcut:
Install Email and on the command line remove (not installed) roundcubemail group
yum remove @"Roundcube web mail"

Besides this an other observation;

It is impossible to reinstall a mail2 package: it conflicts with it self:

# yum reinstall nethserver-mail2-server
..
ERROR with transaction check vs depsolve:
nethserver-mail-server conflicts with nethserver-mail2-server-2.2.8-1.ns7.noarch
nethserver-mail-server conflicts with (installed) nethserver-mail2-server-2.2.8-1.ns7.noarch

I am convinced now versioning at provides and obsoletes is mandatory.

Thank you for the hint! I’m preparing the patch and will try to fix this issue too!

I think we can release the automatic upgrade once https://github.com/NethServer/dev/issues/5583 has been closed.

[davidep (Davide Principi)]

The day has come! The packages have been released and mirrors are synchronizing.

Thanks to @giacomo for reviewing and testing the .spec file patch!

In the goups nethserver-mail-server is still mandatory for roundcubemail and webtop,
IIUC we still have above described behavior…

Is it necessary to keep nethserver-mail-server mandatory?

[davidep (Davide Principi)]

We could remove it from the Roundcube and Webtop group, if it’s already pulled in by the RPM dependency… I’d say yes we can do it!
