Re: Port 25 blocking

Do you have a policy for users who want to connect to their own personal ISP
for email? I would assume blocking port 25 would no longer allow them to
send email via their own ISP, unless you have some provision for them.

We have been blocking port 25 on our firewalls and routers since last summer
because of all the spam mail viruses.  It has help!

Our department has started to discuss blocking port 25 at our firewall
for all machines except for our mail servers. How many places are doing
this? Why did you implement this?
