As of a couple of days ago I have been receiveing the following error message, I do not remember changing any settings or downloading any programmes. What needs to be done to correct this.....

What e-mail client are you using? Outlook? Windows Live Mail? Thunderbird? Something else?What anti-virus software are you using?-B- http://www.officeforlawyers.com | http://www.onenote-tips.com Author: The Lawyer's Guide to Microsoft Outlook

The anti-virus is Norton 360. They are being sent via Email Sender Deluxe as personalised emails to a list of 8 people.

I'd probably try disabling the e-mail scanning function of Norton (which may require uninstalling/reinstalling Norton without that feature) as it can sometimes cause problems.Have you tried contacting Email Sender Deluxe support? -B- http://www.officeforlawyers.com | http://www.onenote-tips.com Author: The Lawyer's Guide to Microsoft Outlook

Thanks for the hint. Yes it seems to be a problem with the Norton settings.
