Norton Email Error 451 4.2.0 Internal processing error

What port number does Telus require that you use for the outgoing email server?

587 - this is where it has been set for a long time. You would ask why?

I am also on Telus and they have insisted that this is a Norton issue. It was lost on the agent that I have the same send issues on my I-Phone which does NOT have Norton on it. Very interested in what solution comes up.

Hi there,

 

Another TELUS/Norton user experiencing the same error.  Happens with replies only and not all of them.  Haven't found a distinct pattern yet.  My messages all appear in the sent box - but haven't not tested to see if they did actually go through.   It has only been happening for about 48 hours.  

 

Thanks.

 

 

Norton Email Scanning supports only Port 25 for sending and Port 110 for incoming messages.  Issues such as the one now being reported are not unheard of when Norton scanning is enabled and ports other than 25 and 110 are being used.  I am not sure why it may have been working perfectly up until now, but it doesn't really matter:  Norton cannot scan Port 587 anyway, so you may as well disable Outgoing Email Scanning if that is the port you are using.

 

Further, if you are using an incoming port other than Port 25, you should turn off Incoming Email Scanning as well - simply disable Norton Email Protection.  In NIS you can do this on the Advanced Screen under Network Protection by clicking the toggle next to Email Protection.  Norton will alert you that the system is at risk.  Hover your mouse cursor over the words "Email Protection" and select "Ignore."  This will stop Norton from monitoring the "On/Off" status of this component so you will not get these protection alerts when the feature is disabled.

 

Turning off Email Scanning does not lessen your protection at all.  All attachments you receive are scanned by Auto-Protect when they are accessed, and Norton will prevent any infected attachments from opening.  Anything that Email Scanning would have detected will also be detected and blocked by Auto-Protect.  Outgoing message scans have no role in protecting your computer, so they are completely unnecessary.  Certainly your recipients are responsible enough to be running their own AV programs, and chances of you sending them a virus are extremely remote, anyway.

It occurs to report another thing that's started happening around the same time - I get a duplicate message, often coming in at a later time, that gets captured in my junk mail folder.   In some cases I will have already deleted the original email in my inbox. This actually happened with the email Norton sent me welcoming me to the community and notifying me of a private message regarding my registration.  

 

Related perhaps?

There seem to be conflicting reports concerning whether this issue is occurring only when Norton Email Scanning is involved, or if if is also happening even when Norton is not installed.  If the latter case proves to be true, then email scanning and port selection would not be the cause of the issue.  Even so, it would still be advisable to disable scanning if you use anything other than Ports 25 and 110.  Scanning does not work with other ports so there is no point in having it enabled.  And some issues can sometimes arise when using alternate ports while the Norton email scanning process continues to filter messages.

Many thanks for the education. I must say that this also points to the general frustration of Norton as bloatware - if you really don't need this scanning, why have it?

 

I have been through the port thing with Telus before - you have flexibility and override capability until something happens - then the Telus tech (usually world class) pushes you back to "safe" house settings on everything.  One of their largest issues is spam control and I suspect they were messing with their internatl controls.

 

  I can recall a simpler and gentler time ten odd years ago when Norton was antivirsus - it now has bloated to running your PC from maintaining the system to backing up files - big joke is that other companies try same trick and you have the UN version of multiple good and bad guys slugging it out. My alternative has been moving to the expensive Apple monopoly which shows there is a place for benovalent dictatorship.

Turned Norton email scanning off and still getting the error within Outlook:

 

Task '*@telus.net - Sending' reported error (0x800CCC6A) : 'Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: 451 4.2.0 Internal processing error'

 

 

I got the same probelsm starting yesterday.  Very frustration and it is with Telus and Norton.  I can't dump Telus yet because I have a contact, but I can dump Norton.

 

Norton has been terrible in the past, but I thought that they got their act together until now.

This morning (April 30) am having the same problem - also use Telus ISP.  It seems to be random.  About half of my messages are getting out.  Some of the errors were replying, others were messages I originated.  I updated Norton to 2012, but that did nothing.  Problem persists.  Others at my house have the same issue on different computers.

The error messages are originating with Telus, not Norton.  Norton email scanning components sit between your email client and your ISP and filter incoming and outgoing messages.  When Norton Email Scanning is enabled, Norton will intercept these error notices from the ISP and display them.  When the Norton Email features are turned off the notices will display in the email client, just as they would it Norton were not installed.  The error is still occurring, even with Norton disabled.  This is pretty convincing evidence that the problem is solely with Telus.

Same issue starting today.

ISP is Telus :( and using Telus mail account.

Using Windows 7 & Livemail

SMTP Port 25

Incoming Port 110

Getting error message regardless of whether it's a new email, forwarded email or reply.  Seems to not happen when I cc myself on the email.  When error message occurs, the email appears in sent folder but has not been sent (I checked with intended recipients).  Also noticed when I checked Norton history that concurrent activity is happening on some emails sent:

Unauthorized Access Blocked (access thread data)

Actor: Windows\System32\services.exe

Actor PID: 540

Target: C:\program files\norton internet security...\ccsvchst.exe

Target PID: 2768

I fixed this issue by opening up Norton and choosing the support tab, choosing "get support".... it then updated and installed something and then all my test emails to myself came through... kind of annoying when I'm a mortgage broker in Vancouver and I couldn't send any emails this morning.

thanks, I tried the get support suggestion, and Norton did an autofix...checked installation etc and everything was fine.  Emails went through for a short time and it started up again.  I will try to call Telus tomorrow as this is very frustrating

 

thanks for all  your suggestions

I'm having this issue too.  I'm using Telus, Office Outlook 2010 and Norton Internet Security 2012.

 

I tried the "get support" suggestion in NIS.  I tried it once (with outlook still running) and my test messages didn't go through.  I shut down Outlook, and everything else, and tried it again and rebooted afterward, without success.  Each time I ran it, it said that it was checking the installation but didn't actually come up with a dialog to suggest it made any changes or reinstall anything.  (I wasn't asked to approve to allow NIS to make changes on my computer.)

 

I started a chat session with Telus and the issue appeared to be completely new to the technician.  Unfortunately, it took 40 minutes to connect with a technician and we had just started when I was called away.  I'll have to try again tomorrow.

What happen??

 

All of a sudden it is quiet.

 

Would really appreciate knowing what happened and what was done to fix it.

 

Is it Telus and/or Norton?

Let's go with the earlier theory that this has happened three years running at the end of April due to something Telus and Norton do in their systems. I agree - all problems have vanished and while I tried the various fixes suggested (turning off email scanning, changing ports, etc), my system is just running fine on all the original settings that were there prior to April 27. Sure glad I get to pay for all this fun!

Yes, it looks ok for me as well now that it's May. Telus could not find an issue and Norton suggested turning off sent e mail scanning but it was still a problem maybe 25% of the time sending e mails and turning off the scanning did not appear to fix it. Odd, maybe it is a late April issue every year.

 

The problem seems to have gone away for me as well. I sent quite a few emails yesterday and all of them went on the first try.
