qmail-taps-extended

Hi Roberto and  THANK YOU for your great work to guide, document and support your Qmail distribution!

I have installed your Qmail release v2024.02.06.

I am using qmail taps feature to log mail sent from user1 to another mailbox in the same localdomain:

F: user1@localdomain.com: backup@localdomain.com

When user1 sends mail to somebody of the @localdomain.com, we receive it 2  times in backup@localdomain.com.

When user1 sends mail to @outsidedomain.com, we receive it 1 times.

And the second experiment:

F: user1@localdomain.com: backup@localdomain2.com

When user1 sends mail to somebody of the @localdomain2.com, we receive it 2  times in backup@localdomain2.com.

When user1 sends mail to somebody of the @localdomain.com or @outsidedomain.com, we receive it 1 times in backup@localdomail2.com.

I saw similar comments for the qmail-taps-extended pach. The qmail-tap patch didn’t have this problem.

Hi Violeta,

I cannot reproduce the issue here in neither situation you mentioned. I don't know if it's intentional, but if I use a control/taps with spaces like in your example it won't copy the emails

F: user1@localdomain.com: backup@localdomain2.com

I'm testing like this

F:user1@localdomain.com:backup@localdomain2.com

or even

F:.*:backup@localdomain2.com

Hi Roberto,

There are no spaces in my real taps control file.

 You can reproduce the issue  if in your taps:

F:user1@localdomain.com:backup@localdomain2.com 

user1@localdomain.com  sends  message to user2@localdomain2.com

Then backup@localdomain2.com receives 2 identical messages from user1@localdomain.com (duplicates).

In summary: the issue appears when the receiver and backup-box are in the same domain.

I would check the .qmail-default and the backup-box .qmail file if it exists

Hello Roberto,

Thanks for your efforts for resolving of my problem. Your advice was correct. The problem was in my .qmail file:

The receiver (user2@localdomain2.com) has .qmail file to anotherbox@localgomain2.com and this was the reason for the delivering of two identical messages. There is a clear log in /var/log/qmail/send for that.

 Once again thank you for your time and support!

Hi Violeta,

this is actually the test I did. I receive only one backup message, as expected

I just installed this patch and unfortunately i am getting duplicate e-mails when the e-mail taps is sending an email locally and remote as well. 

I am missing something or this would be the normal behavior? 

To be more exactly: sender x@domain.com is sending emails towards y@domain.com and z@anotherdomaina.com.

If I am using F:x@domain.com:k@randomdomain.com I am getting duplicate email in k@randomdomain.com

yes the expected behaviour is to get a copy of each email with x@domain.com in the From field forwarded to k@randomdomain.com
