X-BeenThere: freebsd-security@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: "Security issues \[members-only posting\]" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 01 May 2011 23:08:43 -0000 We run our own (freebsd) mail server. It's a pretty classic, old fashioned /var/mail/username setup. We have enabled POP so that certain people can pop their mail from us, and use gmail as their mail client. However, we have no other POP users ... and I don't want POP open to the whole world ... BUT, I suspect there are a LOT of possible IPs that google will use to pop mail from us ... Is there an authoritative list ? Anyone else blocking POP access to everyone BUT google ?
