Who do you trust and for what? Adding various third party CA certificates, i.e. using a PKI infrastructure for SMTP for the general public: Pros: None Cons: * If you ever do certificate based access control, you will be in for a surprise. * MTA's TLS codes are well known for the more populer ones. However, code paths that deal with a lot of CA certs are seldom used. There might be corner cases. On a more general note, please ask yourself "Do I really need a PKI?" and avoid PKI if you can. It is a mess and is not the way forward. -- Eray
