[Exim] unsecure, slow, not 100% RFC-compliant?

Hello list,

I read some weeks this mail-list, websites, and the documentation of Exim
and i think i love it :-).

But i have also read some sites about comparison of MTA's, please read
self:
http://homepages.tesco.net/%7EJ.deBoynePollard/Reviews/UnixMTSes/
and
http://www.geocities.com/mailsoftware42/

there stand Exim will be unsecure and slow, on some boards i become the
information it will not be 100% RFC-compliant - is that true?

I dont want to start a flame-war, and sorry for my poor english and it
sucks :-)
