no email after changed domain to own IP?

Hi, have given 2 domains their own IPs and set dns to reflec new IP address.

The web works fine, but now email is not working when using remote client?

It is working when i use webmail?

accounts on shared IP work fine.

a test via remote telnet confirms this?

Any ideas why?

thanks

 

When you say "remote client" do you mean a client (outlook/thunderbird/live mail etc) from a remote location outside your local LAN ?

If so have you checked that the ports are open on the router/server, and being forwarded from router to server, and that the client is using the correct ports.

Webmail uses port 80/443, where a client will use port 110/995 for pop3, 143/993 imap and 25/587 smtp usually depending on your setup.

 

Yes mean email client.

It is not a port issue as i can connect to other email accounts on the server that use the shared IP, it is just the 2 domains that i have allocated there own dedicated IP address!

I have tried to telnet to newipdomains.com on port 25 and 587 from both remote machine and on the server, but get connection refused error on both?

 

I thought my IP may have been banned, but get same issue using mobile network.

check fail2ban to make sure and does not have any banned IPs

iptables -L -n

Code:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
fail2ban-ssh  tcp  --  0.0.0.0/0            0.0.0.0/0           multiport dports 22

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)

Chain fail2ban-pureftpd (1 references)
target     prot opt source               destination         
RETURN     all  --  0.0.0.0/0            0.0.0.0/0           

Chain fail2ban-ssh (1 references)

RETURN     all  --  0.0.0.0/0            0.0.0.0/0   

tried an unban just in case, but get error

Code:

iptables -D fail2ban-dovecot-pop3imap -s HomeIP -j DROP
ptables: Bad rule (does a matching rule exist in that chain?).

 

A check on mxhealthcheck.com give the domain the all clear !

thanks

 

Di need to edit postfix main.cf and set

Code:

smtp_bind_address
