I use Outlook Express for my e-mail. I upgraded to Norton Internet Security 2010 around 3 May and since 11 May I have been having a problem with one particular e-mail address (different clients at the same organisation address). I get a message from my ISP server saying that the IP address (I think destination address) has been put in an "RBL" list and has not been delivered. I assumed that this problem was due to my ISP's server configuration; today I tried (just for fun) to disable the Norton outgoing e-mail checker and ........ the mail was delivered successfully!! I re-activated the Norton outgoing e-mail checker and the error returned!!!!!
This only happens to one particular e-mail destination but to all addressees at that destination.
Anyone else had anything similar?? or can suggest why Norton should create this sort of problem which causes an error message from my ISP server??
Thanks in advance.
