However I have two problems with the manner in which outgoing email protection is implemented. (This discussion refers to Norton AntiVirus 2011 and 2012.) First problem: Aside from viruses or worms, there are common situations when a non-infected outgoing email may be rejected by the outgoing (SMTP) mail server. These may include: - Emails that are larger than a maximum size allowed by the user's ISP; - Exceeding an ISP's limit on number of emails that can be sent during a period of time; - Suspected spam content; - Etc. From a user perspective, in such cases there are at least two differences in how the attempted transmission is treated, depending on whether or not Norton Email Protections is active. The first difference is that without Norton protection, the error message in

Error Issues written by: Donna Buenaventura•edited by: Jean Scheid•updated: 2/26/2011Most antivirus programs have improved their e-mail scanners, which means sending e-mail with e-mail protection enabled shouldn't be a problem anymore. However, if you are seeing any Norton Internet Security e-mail error messages, try the solutions in this article. slide 1 of 5 Antivirus E-mail Scanner Internet security suite software and advanced antivirus programs include protection to scan incoming and outgoing messages. The security software integrates an e-mail scanner component in the widely used POP and IMAP e-mail clients, such as Thunderbird, Outlook, Windows Mail, Outlook Express or Windows Live Mail. The option to scan incoming and outgoing e-mails can help protect the privacy of end-users from spyware and malware distributors, in addition to blocking unsolicited e-mails, aka Spam. However, some users are receiving error codes when sending or receiving e-mails even with the antivirus email scanner enabled. If you are blaming the e-mail scanner, this should not be case since most antivirus software programs that provide e-mail protection have been improved upon. An example is when a user receives a Norton Internet Security e-mail error code or message. Below are some descriptions of error codes received by some users and how to fix them. slide 2 of 5 E-mail Time Out in Thunderbird When Using Norton E-mail Scanner If you are using Thunderbird e-mail client to send e-mails, you may see a time out error. This problem is not caused by the antivirus' e-mail scanner. Version 3 of Thunderbird has a new setting when sending e-mails. Mozilla has increased the amount of data that the e-mail program can send. To fix the problem, decrease the allowed outstanding data in Thunderbird: Open Thunderbird > Options (for Windows and Linux) or Preferences (for Mac). Click Advanced > General > Config Editor button. You'll be warned that changes are not recommended, simply click the button for "I'll be careful, I promise!" In the window where the variables are displayed, right-click (or control-click, on a Mac) to get a contextual menu. Select New > Integer in the contextual menu. Type network.tcp.sendbuffer > click OK. In the next window, type 65536 > click OK. Close any opened window and try using Thunderbird again. slide 3 of 5 Error Code 452 One of the common error codes when sending e-mail is error code 452. This error code may display any of the below error messages: Email Error: 452 Too many
