Case for "mail delivery failed"

[kshetriamrit@…]

I have a case where there are multiple recipient for a mail. But one of the email is returning "mail delivery failed" email which is again used to comment on the ticket.

And this process is going in a loop.

Do we have any mechanism to control this? I searched but found nothing.

Thanks

At our site we user:

• black_list: MAILER-DAEMON@,postmaster@, mailman-bounces@, MicrosoftExchange.*@surfsara.nl

See https://oss.trac.surfsara.nl/email2trac/wiki/Email2tracConfiguration

[kshetriamrit@…]

Thanks for quick response. I will reconfigure this and will get back to you soon.

[kshetriamrit@…]

Here we have our own email server. And email contains text like "RESOLVER.ADR.RecipNotFound?". The config you sent did not work for me. All emails are sent and received from same user.

I guess there is no need to restart any service. If yes, what is it?

You can send a test mail to a unknown user and see what the mail server gives back. Look in the header of the message to see what your MTA is using and use this in your black_list configuration. The line I send you is in use by our setup. You have to adjust it to your situation or afjust your Mail server to give a proper message.

Ok, here we have random id for failed mail (don't know why). So putting it in blacklist might not work.

Also I noticed something. Can we not specify that only users that are registered can create ticket? or user that are in CC so that this can be eliminated or it can be more secure since other person cannot create ticket?

Replying to kshetriamrit@…:

It is just a match, there is no familiar part in the sender address?

Did you read the configuration options or documentation?:

• https://oss.trac.surfsara.nl/email2trac/wiki/Email2tracConfiguration#PermissionSystem

[kshetriamrit@…]

Hi, before going to permission, I now have common text on sender. I have put the string in black_list but it did not work. Is there any service to restart?

For permission, I am using trac for ticket_permission_system. But somehow it is not performing accordingly. I will look into it. But currently black_list is still not working.

[bas]

To track this down. You can put email2trac.conf in debug mode. Then the mail message will be saved in /tmp and the debug output is logged in the syslog. After that you can test why black_list is not working on the commmand line:

• email2trac -n -v -d -p <project> < /tmp/save_message

search for black_list. Can you send my the black_list line?

and I have placed "postmaster@" in black list.

In which email header field is postmaster@ located, eg:

• Reply-to
• From
• ...

It exists in From:

Which version are you using? I just tried it and everything works as expected:

• email2trac.conf

Sorry for the late response. All the changes I made was on the other file. Original config file where in different location.

It is working as expected.

Thanks for your support.

[bas]

Glad that everything works as expected.
