[Zope] sendmail in standard_error_message

Mon, 3 Dec 2001 14:22:12 +1300

Hi All,

When I add a dtml-sendmail block to my standard_error_message, I no 
longer get the custom error page at all, but the built-in one (headed 
up "Site Error." I read in the archives that this can be due to the 
standard_error_message object itself raising an error, but I have put 
the code in another object and it works fine there.

Any idea what I've done wrong? Any help would be greatly appreciated. 
The code in question is included below.

Thanks a lot,

Arian

Here's the code for the standard_error_message object I'm using, 
which tests for a NotFound error to treat 404 errors differently. If 
the sendmail block is removed, it works fine. The mailhost object 
*does* exist -- the sendmail block works perfectly when used 
elsewhere.
