The mailing list for listmasters using Sympa

[Gavin Younger <address@concealed>]

Radu,

This became a problem with yahoo (and some other domains) last year. There 
was some lengthy discussion around this on this list, I seem to remember.  

Take a look at http://www.sympa.org/manual/dmarc which explains the issue 
further. 

If you are running a recent version of sympa, (6.1.22 or higher), then a 
patch was provided to solve this issue.

In particular, take a look at the 'dmarc_protection_mode' parameter (and 
related parameters)  
http://www.sympa.org/manual_6.1/conf-parameters/part3#dmarc

You need to be running 6.1.22 or higher (maybe a reason to upgrade?   :-)  )

Hope this helps.

Regards,
