Apologies if this has been answered elsewhere.
I run a local web server in my house on which are some classic ASP scripts that use CDOSYS to send e-mail via SMTP to my ISP's mail server [i.e. objMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/con...endusing") = 2].
For no apparent reason, a couple of days ago this spontaneously stopped working, but now if I disable Zone Alarm, it works just fine again. It does not make any difference whether I use SMPT authentication or not. Therefore I think the problem is with Zone Alarm.
I am not familiar enough with the underlying workings of IIS to know how to force/enable attempts by CDOSYS get through the firewall, which I imagine is what is being stopped now. This is very random and really annoying, so does anyone have any ideas? Thanks in advance for your help.
Operating System:Windows XP Pro
