Norton Email Error 451 4.2.0 Internal processing error

I have recently had difficulty sending emails from my PC and I have had this email message displayed or not displayed and the intended recipients advise me that they have not received my emails.

 

I use NIS 2012 with Outlook 2007 and my ISP is Telus, a telephone company.

I receive no error messages from Outlook nor the ISP and the error message only comes from NIS.

l just got off the telephone with Telus as to support and they state that this is a Norton issue.

 

Any recommendations would be appreciated.

 

Thanks.

Hi juliaroberts,

 

Message notifications returned by your email service provider will be displayed by Norton, so the fact that the notices appear in a Norton alert box do not necessarily mean that Norton is generating the error.  To see if Norton is the issue disable Outgoing Email Scanning (Settings > Network > Message Protection > Email Antivirus Scan Configure [+]).  If you are then able to send, you can leave this setting disabled.  If the problem persists, you should contact Telus again.  Does this happen with all messages or only particular ones, such as those to specific recipients or with attachments?

I've had the same problem with a few of my outgoing emails today. I'm using NIS 2012 and my ISP is also Telus. It can't be a coincidence that two Telus users would start having this problem. It must be a Telus issue. So far, I have been able to resend emails and have them go through.

Thank you very much for your prompt reply.

 

Recently, I have forwarded the email again with a cc to myself and the email did go through (similar to the other gentleman that also commented that he had a similar issue).

 

I am thinking that I probably have had 6 or 7 emails like this; I was on the telephone with someone in northern BC and I resent the same email 3 times to the same account however on the 4th time when she gave me another account (coincidentally a Telus account) then the email went through.

 

I run a small home based business and it is really important to be able to communicate with your clients or prospective clients.

 

I will continue to monitor the issue, however, since I have alerted Telus I suspect that they will also monitor my issue in the background ...

Hi,

I understaand how important email is to your survival. May I suggest that you take at least one deep breath before hitting the send button. During that time check to see that all of the elements required by the system and ISP are present. Mistyped addresses are my weak point. Also be careful when sending messages to several clients. Don't run afoul of the ISPs spam filter. One workaround for a long list is to use the BCC option for the list and your own address for the TO box. This usually slips past the filter.

I am also assuming that you are using an email client so that your address book is behind your Norton firewall.

As has been said many times before the most inprotant security device you have is a fully engaged chair/keyboard interface.

Stay well and surf safe

Hey Group

Bill_Holmes and bennettkelly, could you please click on the ME TOO button in the first post in this thread.  Norton is tracking recurring problems and you'd be saying you have a similiar problem.

Re: Norton Email Error 451 4.2.0 Internal processing error

I just joined this club about a week ago - random terror by Norton sending emails (Outlook 2010 / Telus provider). It seems to be worse on email lists or a particular address - however whenever I trace it to a particular address, the resend works perfectly.  I had Telus verify that my email accounts are ok. Can't find anything on Norton Help site.  Any ideas appreciated.

Re: Norton Email Error 451 4.2.0 Internal processing error

I have done some further testing.  My home Lan is 50% PC and 50% Apple.  This issue does not happen on Apple as there is no Norton product there.  There is no issue on either PC or Apple when I sent through my Gmail account - only Telus. A friend, also on Telus, reports that various attachments for his baseball legaue are being stopped or stripped or the email stopped.

 

Therefore, while there could be a conflict between Telus and Norton, my bet is that Telus has changed part of their system or have issues and that is hub of the problem.  I just don't understand why sending via Telus on an Apple does not have same issue as on PC - perhaps this is due to the randomness of problem.  Back to Telus to see if there is a problem there.
