Cable Forum - View Single Post - Can't send email

For the last ten days I haven't been able to send emails via mt NTL broadband STB. Although I can send emails via telephone ISPs and NTL's WEBMail.
I received an error code of 452 Email rejected by ISP code 0x800CCC6C. I normally use Outlook Express but I also tried Mosilla Thunderbird - same effect.

Got through to NTL Tech (email) support 3 times. without any solution.
This morning they got me to change the smtp server address from smtp.ntlworld.com to 62.253.162.40 ie its TCPIP address. Email now works, but am I running into danger leaving the TCPIP address in the account settings?

If I ping smtp.ntlworld.com I get a TCPIP of 212.250.162.8 (pings ok). I do a reverse lookup on 62.253.162.40 and it tells me that it is smtp.ntlworld.co.uk. How is it possible for one URL to have two TCPIP addresses?
