Simultaneous SMTP connections

Does LuxSci's High Volume service support concurrent SMTP connections?

Yes, LuxSci does allow concurrent (simultaneous) SMTP connections so that you can do bulk sending in parallel streams for faster mail processing and sending. Accounts on our shared High Volume servers have a limit of 25 concurrent connections, and our dedicated High Volume servers have no specific connection limit, only what the hardware can handle. Using multiple concurrent connections for optimal sending performance works best when you have a few (3-5 in shared; 10-20 in dedicated) connections set for sustained sending--the high limit of 25 connections is to allow for temporary connection spikes.
