If it is just POP3, then it will be overkill. But how are the messages
getting there? You'll need at least LMTPd. Are your POP users sending
mail through this same server, using ESMTP+TLS? If so, thats a bit more
encryption.

Our experience is that this system would handle both just fine, but you'd
be better off increasing the memory to handle the large mail queues and/or
large POP downloads, which are both loaded into memory for processing.
Memory is cheap these days, get at least 4gb.
