Redmine

422 is an HTTP error added by WebDav. Check your svn/apache/webdav conf.

Umm, there's no Webdav involved.

Hi Thomas, could you be more verbose? I really would like to get this going.

Try your setup without apache: you'll see that you're WebDAV will not bother you...

I have the exact same error, but I don't understand any of the advice that Thomas Lecavelier gives. Can anyone help further on this problem?

I'm having this problem to. I'm running redmine from my local machine, so the url to access it is http://localhost:3000

Reading redmine's log redmine/log/production.log there is this entry:

The end of the log message says: 422 Unprocessable Entity [http://*localhost*/mail_handler]

Shouldn't it be http://localhost:3000/mail_handler ?

I'm sure that postfix is working properly.

I couldn't solve it yet, so I appreciate if anyone has a clue.

Hi Henrique,

I had the same problem with 422 error, though my goal was somewhat different (I tried to make a direct HTTP POST call to my redmine installation from Java environment to create an issue).

I can suggest the following:
1) Make sure your message body ends with a "newline" symbol ('\n');
2) Try doing the following trick: specify Project and Tracker parameters in email body and make sure they are the last lines in the message, e.g. you should get something like

Processing MailHandlerController#index (for 127.0.0.1 at 2009-03-02 12:30:57) [POST]
  Session ID: 7199ffdaa8111b282c52792d878660fa
  Parameters: {"action"=>"index", "allow_override"=>"",  
"controller"=>"mail_handler", "key"=>"S66xCpNzSxfXYt4toiu9", 
"email"=>"From henrique@localhost  Mon Mar  2 12:30:57 2009\n
From: henrique@localhost\n
Subject: Test3\n
\n
One more test3\n
\n
Project: myproject\n
Tracker: bug\n
"}

Please, note the absence of "issue" HTTP parameter.
I do not know if these tricks are absolutely necessary neither do I imagine how they work, but this makes the job for me quite well and no more 422 errors

i'm having the same issue.
This error only appears if mail is sent by an user which is not registered in System.
Any ideas how to solve that problem?

Not sure if this will help anyone.. but at least I'll have an answer to my own question when I look for it again ;)

Whatever the email address is that you are sending the mail from needs to exist and it needs to have access to the project that you are sending it to..

Here is an example for what we are using for qmail with vpopmail..

cat .qmail-redmine-projectname | /usr/local/vpopmail/domains/domain.com/rdm-mailhandler.rb --url https://support.domain.com/redmine/ --key 6lFFAHvxFASnh654321 --tracker=support --project=projectname

so sending an email to redmine-projectname@domain.com will try and inject it into redmine as a support tracker.

https://support.domain.com/redmine/settings?tab=authentication

self-registration: manual account activation

It might be b/c of the self-registration settings.. but I have not had time to play with it..

Again hope this helps someone..

Thanks for redmine ;)
