Our client has Dynamic Public ip address, as cisco support informed as that ISP ADSL blocks smtp port 25. with this, how can i configure and address this issue for their internal domain clients can send/ receive mail from/to outside world?
registered domain name is: domainname.org
internal root domain: domainame.local
host A record: smtp.domainname.org (pointing) to client router dynamic ip address
> host field (entry) - domainname.org
>data (entry) - smtp.domainnamer.org
Please advise. Thank you.
