I'm unable to send emails because of the ip lookup
“ hostname 105-228-156-175.south.dsl.telkomsa.net does not resolve to address 188.8.131.52: Name or service not known"
Please urgently assist.
@Mich7879, the 105.x.x.x will be your dynamically assigned IP from the ISP and could change each time your router reconnects. What are the SMTP settings you are using in your mail client?
