Yes. In fact, you don't even need a patch for IP-based virtual domains. The patch is for name-based ones. > Is there a patch out there that can support external paths? > (i.e. domain:<server>:<port>)?

No. I suggest that you search for "POP3 proxy" on Freshmeat and Google. Since many POP3 proxies are meant for end-users, and this is not what you need, you may want to add extra keywords, such as "server-side". If you put popa3d behind a proxy like that, you may need to increase popa3d's MAX_SESSIONS_PER_SOURCE setting, because all of your connections will be coming from a single IP address (that of the proxy). Hopefully, the proxy implements its own anti-DoS measures (OK, most don't...) If you like, we may help you set this up - including consideration of your specific needs, choice of existing POP3 proxy software or/and custom programming (maybe a rework of popa3d), testing, deployment, and maybe maintenance - as a paid service. Please let me know off-list if you're interested.
