HELO problem during sending message
When thunderbird tries to send email error occurs: "Helo name contains an IP address (HELO was [192.168.1.17]) and not is valid." What is quite funny - the error appear only at my home on my home connection. What I am at work or connect thruogh my smartphone - everything is ok.
I tried to restart my home router but it didn't help. it is worth adding that the whole problem started to appear at the moment when admin transport domain to another hosting with new DNS.
HELO problem only appears at thunderbird. Sending e-mail through mail in the browsers work fine.
