Hi,

Another approach that you could consider is using SASL for SMTP, and let the SMTP server add a "X-Authenticated-User" header.

This way you now exactly what user that send an email, that way is even more bulletproof for tracking abuse ( if an user group is behind of NAT for example )

Roundcube already supports logging into SASL and Postifx + Dovecot for SASL is a nice way to get this up and running.

Cheers

Hi,

I operate roundcube on a larger server with possibly groing amount of users - therefore I'd like to cover my back and have roundcube add an X-Originating-ip header or something equal to outgoing messages, in the same way that yahoo and hotmail do (actually gmail doesn't do this and this is getting them blacklisted by spamcop all the damn time).

Having the ability to add such a header will allow me better to track abuse of my servers and would make roundcube more usable in larger deployments. I'd appreciate it if this feature will be considered ;^)

Auke
