Can't open port 587 on plesk 10.x

empati

New Pleskian
Hi,

I'm using Plesk 10.4.4 Update #24 on a linux machine installed CentOS

I'm trying to open port 587 for mail clients. I have added a new rule by plesk firewall for port 587.

It's:
/sbin/iptables -A INPUT -p tcp --dport 587 -j ACCEPT

But clients still can't sent any mail via outlook or other mail clients.

Do you have any advise for me?
 
But can you see that port is open on local server? Check it on Plesk server with

# lsof -i tcp:587

If port is not open try to fix it with

# mv /etc/xinetd.d/submission.psa /etc/xinetd.d/submission_psa
# /etc/init.d/xinetd restart
