From: f0x at squirrelsoup.net (Gabe Arnold) Subject: AW: Windows Messenger Popup Spam on UDP Port 10 26 I run off of RCN and they have recently blocked all outgoing port 25 traffic unless someone buys a static IP for another $20 a month. Although I agree that blocking 25 outgoing is nice, I pay for internet access, not for access only through certain ports. Due to the nature of my setup, I was getting a static IP anyways, but I think the $20 bucks is a lot. In the end the decision was deal with port 80 and 25 blocks or pay 20 a month. I pay the 20, but I think I'm getting nailed in the ass. --Gabe * Nils Ketelsen (nils.ketelsen@...hne-nagel.com) wrote: > At 11:16 23.06.2003 +0200, vogt@...senet.com wrote: > > >> A professional ISP does not block any port.
