Email Error 421 with Internet security 2011

I get an occasional email error message when sending an email, saying "Email Error 421 - could not send - try again later."

 

I am using Microsoft Outlook 2007 with Windows 7 64-bit, and Internet Security 2011.  IS 2011 is an updated installation over IS 2010.  This was never a problem with IS 2010.

 

I looked for online solutions, the only thing I found was on the Business side of the Norton site, which said this was a known error but unresolved at present, and  to Turn Off Email Scanning.  I did this, but have no idea if it solved the problem since it is an intermittent issue.  Also, IS now says "attention needed" and asks me to "fix it now.".

 

Any suggestions are certainly appreciated,

I can not confirm if the error 421 is a known error or not, but you can get rid of the "Fix it now", by left clicking on Email Scanning (alongside where it is shown as off) and click on "Ignore".

Hi CCamp,

 

SMTP error 421 usually means that there is a temporary problem with your email service.  The issue is with your email service provider rather than with Norton.  Notifications from your ISP are displayed in a Norton dialog box rather than your email client because Norton, sitting between your client and ISP, actually receives the notice from the ISP. 

 

To clarify yank's reply, in NIS 2011 hover your mouse pointer over "Email Protection" on the main Norton window.  This will bring up a popup that you can click to have NIS ignore the fact that you have email scanning turned off.  This will stop the "Fix Now" alerts.

THanks for the "Ignore" fix.

 

However, I don't think this is an email server problem, it has never been a problem before.  And in retrospect, I can't say whether it was a problem with IS 2010, it was only in place briefly until it updated to 2011

 

It is indeed a known problem for IS 2010, see below (updated 10/18/10):

Hi CCamp,

 

Welcome to the Norton Community.

 

The service article you referenced indicates the problem is specific to "Dodo" ISP. Is this the ISP you have?

 

Bear in mind that this article talks about a very generic symptom and it is easy to think from that that any time you see this error it is because of Norton but that is not the case.

 

These errors do come from your ISP and so unless you have the particular ISP referenced in that support article you should check with them on this error.

 

Best wishes.

Allen

Re: Email Error 421 with Internet security 2011

I have nie 2011 on two pcs, one running vista and one running xp.  On the xp pc I often get the error 421.  The nie2011 settings are the same on each pc.  Email on both pcs go through the same isp (earthlink via time warner broadband)  for mail. I use thunderbird on both pcs.

 

Any ideas as to what causes this?

Hello rerde

 

Have you tested to see if this problem would occur on both computers by sending identical emails at the same time to yourself or to someone else? This error can also occur when there is a time out with your email server. Once again though, it is a problem either with your email server or the one you are sending it to. Norton is just providing the message to you.

Success always occurs in private and failure in full view.

I have sent identical emails to the same recipient on using both pcs and got the error message on only the xp pc.  But, again it does not happen all the time so it is difficult to test.  So why does it happen on only one pc?  Same ISPs and same recipient.

Hi rerde,

 

This may be one of those rare cases where NIS is causing the issue but as you said since this is intermittent it is hard to say at this point.

 

My suggestion would be to work with your ISP in sending a few test emails as appropriate. When you get the error message they should be able to confirm from the logs on their server if the message orginated from them or not.

 

If the ISP comes back and says they did NOT generate the message prior to you receiving the notice then I can notify Symantec and ask them to check further on this.

 

How does this sound?

 

Best wishes.

Allen
