I had a system where it failed (also silently) every first time after reboot.

I just moved to an external method that used /usr/sbin/sendmail as I did 
not have enough time to start debugging. Telnet to port 25 had just a very 
long (>30 sec) startup time, probably some DNS problem. 

AFAIK Zope does not (for some unknown reasons to me) use pythons SMTPlib 
but has rolled their own smtp interface.

It has also been reported to fail with MS Exchange server, which someone 
fixed for himself by swithing to smtplib. IIRC the patches were also posted 
to zope or zope-dev list.

IMHO the right solution for Zope would be swithing to smtplib, and if there 
are faults then fix them there (and maybe include fixed smtplib with Zope 
until fixes are included in mail python distro). There is no need to invent 
to similar but slightly and differently broken wheels, at least in Open 
Source Software there aint.
