[Zope] slow authentication popup in 2.5.0: dtml-sendmail in standard_error_message on winnt 4

[Jens Vagelpohl]

what happens is that standard error message gets called whenever someone 
authenticates for the first time, meaning whenever they get the 
username/password popup. even though you never see the rendered 
standard_error_message its code gets executed.

your standard_error_message tries to send mail and that's where the DNS 
lookup stuff comes in. i have to second chris in his opinion that this is 
due to DNS lookup problems on that particular machine.
