Sorry if this is a silly question but I've not found anything via Google or zope.org. I am using a MailHost in a Python script. I need to trap error conditions. When I run without trapping I can get exception SMTPSenderRefused. I inserted trapping - eg try: context.mailman.send(vmessage,mto=vto,mfrom=vfrom,subject='Message from web site') except SMTPSenderRefused: vsenderok=False else: vsenderok=True This gave error global name 'SMTPSenderRefused' is not defined I tried importing smtplib and adding it to the except line and then got a permissions problem. You are not allowed to access SMTPSenderRefused in this context I'd appreciate any help with this. Regards Tony
