Dear Noel,I think this is a nice feature you ask there. If I follow you, you would request that each time you send an e-mail to a recipient, this recipient has to be automatically whitelisted for whatever email he would send you in the futur. Right?
I'll think about an implementation of that in my greylister... Best regards, Nicolas Le 21/08/2014 23:30, Noel Jones a écrit :

To be clear, although I have the local Postfix configured to use many different public blacklists, and also some local domain-based blacklists (in which I have blacklisted all of yahoo.com, for example) what I am looking for is something that would effectively override all those filters for specific e-mail addresses that I have previously sent outbound mail to, e.g. <myrfriend...@yahoo.com>. I'm guessing that I am far from the first person to have wanted such a thing, but has it already been built? Regards, rfg P.S. I am agnostic with respect to the level of specificity required. For example if I sent something to <myrfriend...@yahoo.com> and then that address became whitelisted for _all_ local recipient addrsses, I think that would acceptable, even if (as should be obvious) it might possibly be better to have that address only be _selectively_ whitelisted, i.e. just for <r...@tristatelogic.com>. Either way, an automated whitelisting thing would be useful... ... but only if it works with Postfix.amavisd-new has a "penpals" feature that integrates nicely with postfix as a pre-queue smtpd_proxy_filter, or a post-queue content_filter. I don't use this particular feature, but amavisd-new is solid software. http://www.ijs.si/software/amavisd/ As an alternative, I don't suppose it would be much trouble to convince fail2ban to add outbound email addresses to a database to use as a postfix check_sender_access map. But I don't know of any existing fail2ban filters for that. This would still be subject to spoofing. -- Noel Jones
