Hi all I'm having fun with Tracker (a Zope product) -- certainly it's looking to be a very useful tool for us. But I'm having a problem submitting issues. I get this error when trying to submit an issue: Error Type: SMTPSenderRefused Error Value: (555, 'syntax error (#5.5.4)', 'julian@edreams.com') We sniffed the header and it seems that the mail line below is the culprit: mail FROM: <julian@edreams.com> (what you can't see is that there's a rogue space after <julian@edreams.com> which causes the syntax error on our server) Tracker uses the smtp libraries in Zope. Anyone encountered this kind of problem before? Any suggestions about how to fix this? Either in code, or what I have to do to configure it differently...? thanks so much in advance! PS if I wanted to make a change to the source on my machine, do I have to compile it? I see these PYC files everywhere but I thought Python was an interpreted language? How would I make a change if I found that I had to tweak the code a little? -- Phone: +34-93-508-8550 or 667-914-832 if urgent
