Error 421 enable to access outgoing email

[Jonessie]

Hi,

I have a VM account and one of the email account my I set up for my brother, so he can have a seperate email account. He's just had ** installed and I set up his email account for him but when we try to send email it comes up with Error 0X800CCC67 Error 421 which if my memory serves me correctly is similar to error 550 which would be authentication.

Now he is using another ISP but the email account is owned by me on my VM account but connecting through ** I am certain that VM does not block their mail servers and I am 99.9% sure that ** does not block their either.

I checked it was not Norton, I can ping po.ntlworld.com and smtp.ntlworld.com I can also ping the IP address of the mail servers and well. I can telnet both to 110 and 25. somebody is blocking the outgoing mail server.

Any ideas.

You can only send email through a Virgin/NTL smtp server if you are using a VM ip address. It's a spam prevention feature, common to a fair few ISP's.
You will need to get either a mail account from the new ISP or a gmail account to send mail outbound.

yeah I thought as much, I advised him to use webmail for his email account which is on my VM account and use his new ISP for his other email. Thanks for that much appreciated.

Or you can possibly just use the outbound mail server from the new ISP to send e-mail, and still use the ntl pop server to collect mail

Once the nltworld migration to google is completed later this year he can swap back to using the Virgin SMTP server as that will then allow access from anywhere in the world as username and password is required
