dovecot services problem 2006-04-23 - By lstar
Back
Hi All,
I would like to block the pop3 services.
In dovecot configuration, I modify the statement 'protocol pop3 pop3s imap
imaps'
After restart the service, I use nmap to deterfine which port is open.
I found that port 110,143,993 and 995 also open.
If i need to restrict some domain cannot access pop3 services, I should set the
iptables to block all above ports.
Or I only need to block 110 port that 's ok
On the other hand, if i want to use tcp wrapper to block pop3 services for some
of domain , how can i modify the host.deny
Regards
lstar
