Title: External POP3 access does not work in SME 7
Post by: mcm on July 13, 2006, 12:27:22 AM

Hi

After installing SME server 7.0 final in server-only mode I can not access POP3 from external IP addresses. I have the SME server behind a firewall and the NAT and firewall rules are in place for port 110 (on the border firewall). I can access the POP3 service form my local network (192.168.1.x) but not from public IP's.. When I do a "telnet SMEserverIP 110" from inside I get a: +OK 4xxx2.112xxx31xx@xxx.xxxx.xxk> but when I do it from outside I get no connection. Please help me opening my pop3 service for the internet.

my network setup:
Internet ----->  Firewall -----> SME server 7

The pop3 access worked with my old SME server 6.0 and nothing else has changed in my network.

Best Regards
MCM

Did you enable POP3 Access for External sources from your Server-Manager.

Only allows Local on a default install.

By default SME7 will only allow POP3 access from the local network. If you set the email settings to be 'Allow Private and Public' then you have POP3 access from the local network and POP3S from the public network.

POP3S uses port 995 not 110

When I do a:
[root@xxxx ~]# config show pop3s
pop3s=service
    TCPPort=995
    access=public
    status=enabled
[root@xxxx ~]# config show pop3
pop3=service
    TCPPort=110
    access=public
    status=enabled

So everything looks fine, but it does still not work form external IP's om my SME7.0. I also tried to change my router/firewall rules back to my old SME6.0 IP and I works fine from outside. So it is not the rules that is the problems I only change the IP address in the Nat&firewall rule.

I did enable POP3 Access for External sources from my Server-Manager.

So - have you

port forwarded 995 to the mail server on the gateway
opened 995 on the gateway
set up the external clients to use 995 rather than 110

?
