Just to say that i have to use sendmail as i am designing a system which will sit on a server which is already running sendmail for other processes (ie consistency needed).
I have decided to use Net:SMTP because of its error handling and better features. However i am in two minds about wether to use Mail::Bulkmail for the bulk send or limit the use of modules used by looping through the Net:SMTP mail send i already have for bulk mail. My only worries here are obviously time and sturdyness.

Note that you can use qmail and install a replacement for the /usr/lib/sendmail binary to keep other programs working.
