I did a few (non-blitz) applications that sent e-mails. The biggest problem by far was that some accounts had very tight spam controls (hotmail, yahoo etc) and would often not accept or would file them under spam.
I sorted it in the end but it meant having special rules (and simpler e-mails) for those type of accounts. Pain really.
