SMTP not working about docker-redmine HOT 18 CLOSED

@servermeta what is the problem with SMTP? Does the application not work if SMTP settings are not specified or something?

from docker-redmine.

When submitting a new issue it returned me a white page stating that an error just happened, and inviting to check the logs.

In the logs I found:

Started POST "/projects/test/issues" for 94.23.XXX.XXX at 2014-08-26 10:17:32 +0000
Processing by IssuesController#create as HTML

Completed 500 Internal Server Error in 370.2ms

Disabling email sending on issues updates fixed the error that prevented me from creating a new issue.

If you want I can try to check why SMTP doesnt work, or I could give you the SSH access.

Have you configured SMTP with a Google account?

No, but shouldnt there be a graceful default? Is it desired that the application crashes without SMTP?

from docker-redmine.

@servermeta yes, I have tested with google SMTP settings.

from docker-redmine.

@servermeta let me just check what happens when SMTP settings are not specified

from docker-redmine.

@servermeta not specifying any smtp settings seems to cause a 500 error. will look into this issue. However there is no resolve for wrongly configured SMTP settings.

from docker-redmine.

Well, no SMTP configuration should lead to SMTP not working, not to Redmine not working. Not everybody is knowledgable about stuff, think about all the small businesses that could benefit from docker and redmine, also thanks to their low entry-barrier.

from docker-redmine.

@servermeta your right. will probably add a new config option to enable or disable SMTP. Will try to automatically figure out if SMTP should be enabled (for backwards compatibility) so that existing users dont freak out when they stop receiving mail notifications :)

from docker-redmine.

@sameersbn One possible solution could be a bit of logic in the Dockerfile. If no SMTP is specified, default SMTP is local SMTP, which delivers to a blackhole.

from docker-redmine.

@servermeta you mean install sendmail or something locally?

from docker-redmine.

@sameersbn yes, but there are more lightweight solutions, like smtp-sink (part of postfix, but you dont need the whole package), or a python one liner:

sudo python -m smtpd -n -c DebuggingServer localhost:25

from docker-redmine.

@servermeta yes.. but whats the point of having it if the mails are not going to be delivered anyway.

from docker-redmine.

@sameersbn graceful degradation. Usability. Without some sort of SMTP redmine fails.

I think you should never remove MySQL and add this kind of SMTP failover to improve usability.

Think about the small businesses :)

from docker-redmine.

@sameersbn btw you are the boss, you are doing an excellent work, so you should feel entitled to choose as you see fit. Mine are just suggestions.

from docker-redmine.

@servermeta I still don't understand. I have added an option called SMTP_ENABLED which defaults to false. Which when not enabled, is not going to deliver mails.

You mentioned that without any SMTP configuration redmine fails. If that is the case you have a point. Can you direct me to a use case that exibits this behaviour?

Regarding the mysql removal. I am not too sure that I will be removing it. It is very handy for me to quicky spin up a new container to test out user issues. So its a win there.

from docker-redmine.

@sameersbn Sorry we misunderstood each other. The SMTP_ENABLE flag completely cover the use case. Thanks for your work.

from docker-redmine.

@servermeta will close on merge
