IPv6 SMTP

Right, however I am using an extremely modified version of Qmail that 
tie in to numerous other systems that had to be manually patched in 
order to get the entire system to function the same way that the 
production equipment outside the lab work.

Again, I could have just installed Sendmail and out of the box had an 
IPv6 enabled MTA, but that would not suit the requirements of my 
infrastructure.

Each environment has different requirements, and need different 
implementation tactics.

I envy those who have systems (email, web, DNS etc) that require only 
applying an IPv6 address to just have it work. Then again, if that were 
the case, I wouldn't be as excited with each milestone ;)
