I would assume that your DL’s
have your own domain name in the SMTP address. If your DL’s are not assigned
your SMTP domain that is listed in your SPF, then of course they will fail. Are you assigning different SMTP
Alias’/domain names to your DL’s than what you actually host?

Fernández Hello, Perhaps some of you have this scenario in your exchange
organization and I would like to know how you accomplish it: ·
We have exchange distribution lists with
external members (contacts) ·
Other external users write to these list The result is that out domain is sending mails impersonating
an external domain. If destination domain use SPF (as we do) will drop down the
mails believing we are spammers. How do you solve this situation? Thank you very much for your help. ---------------------------------------- David Sierra Messaging Administrator JCYL (Spain) ---------------------------------------- |
