Dear all, I have a question. We have a mailserver that only accepts incoming SMTP connections from our anti-spam appliances. So far so good, this is done at the tcpserver level. So default is :deny.
Our clients, however also need SMTP functionality so we've set up the same server with SMTP Authentication, however that wont work, since by default all connections other than those from the Barracuda are blocked. We experimented with pop before smtp, but those results are not satisfactory either. The reason we block by default is that sooner or later spammers connect to the server directly rendering the anti-spam appliances completely useless. (or at the very least ineffective) An option for us to setup a different server that only handles smtp functionality for our client, however the problem then is that a domain needs to exist on two servers. one for the popbox and one for smtp authentication to work. Or is it possible for the vpopmail to connect to the database on the other mailserver for authentication or would that be too slow? Does anybody have any other suggestions perhaps? Thanks, Sincerely, - Wouter van der Schagt !DSPAM:47fdd050120507919821043!
