Please provide docker images for clients too

[micw]

Hello,
could you please add automated builds for the greenmail docker client images to docker hub?

Thank you very much,
Michael.

I wanted to add the clients to our docker compose file so it is easier to look at the mails when developing. That would be awesome if they would be provided via docker hub.

@derTobsch : I'm thinking about a separate GreenMail repo containing GreenMail + clients dockerized combinations.

@marcelmay what would be the benefit if you would do that instead of keeping it in the same repo? If you separate it you need a job IMHO that updates the other repo after a release so you do not have to do that manually.

You might want to have a look at this docker-compose file:
https://github.com/JensKnipper/greenmail-example/blob/main/docker-compose.yml
If you need some explanation, I also wrote an article about it:
https://jensknipper.de/blog/greenmail-mock-mail-server-dev-setup/

There are also some examples in the repo:
https://github.com/greenmail-mail-test/greenmail/tree/master/greenmail-docker/clients
In my opinion they are not best practice anymore and should use the official clients' docker images.
I am going to create a pull request where this will be fixed soon. I am also going to adjust the documentation, so this part of the repo can be found easier in the future.

Thx alot, @JensKnipper ! Added your article link to the docs and look forward to your PR.

Those docker clients were created usually only created for reproducing issues, and are not really maintained.

Hey @marcelmay,
thank you for linking my articles.

I am not finished yet, but I would like to discuss some things with you guys:

• Roundcube: just finished, I hope you like the way i documented it - #270 use official roundcube docker image #414
• Squirellmail:
  • dockerfile is not working anymore as Ubuntu 16 is out of support
  • squirrelmail is not in the repos of current Ubuntu versions anymore
  • the latest tag on svn is from 2011, not an option in my opinion
  • checking out the svn trunk might be an option
• Rainloop
  • solidnerd's image as not been updated in 5 years
  • use his dockerfile to create new ones might be an option
• Nodemailer:
  • not really a mail client, is this still needed?
  • I would suggest removing it

What do you think about that?

[marcelmay]

@JensKnipper ,

thanks alot for the PR and your input.

• Roundcube: Merged your PR.
• Squirellmail, Rainloop: Any further PRs welcome.
• NodeMailer: You're right, should not have ended up in the repo. Now its removed.

In general, I was thinking about moving these client integrations into new repo , eg https://github.com/greenmail-mail-test/greenmail-client-integrations (better name is open for suggestions). To keep the core repo more lean and focused.

Sounds good :)
The name also sounds good to me!
