Yeah... I really dislike SMTP proxies. If I was, say, trying to protect 
an Exchange box it'd kind of make sense, but then why not use a 
gateway/proxy postfix machine (as I currently do for sendmail)?

I'm really looking for something that plays with the MTA rather than 
works without its knowledge. I'll trust postfix to know how to handle it 
when things go wrong, and how to detect if a helper fails. I'm not so 
confident about an SMTP proxy.

As for things going pear shaped, it's very important to be able to tell 
when things are going wrong. Good, reliable logging is important. That, 
for me, is another reason to want the MTA to be the first point of 
contact for incoming mail.

I appreciate the suggestions, but I don't think I'll be trying the SMTP 
proxy route.
