MultiSendcon is an email distribution software that divides emails from Exchange to distinct SMTP smart hosts. The distribution is done based on the sender's address and includes different SMTP AUTH username and password authentication.

MultiSendcon is a software that distributes email sent out from your Exchange server to separate SMTP smart hosts based on the sender address. Therefore, you can now have outgoing emails routed through different SMTP relay servers. For example, if you wanted your company's email addresses to go through your web space provider's SMTP relay server while using Google's SMTP relays for your Exchange-hosted googlemail addresses, MultiSendcon can do this automatically.
The best part about MultiSendcon is that it's easy to install and use. Once installed, all you have to do is configure the software according to your preferences, and you're good to go. Overall, MultiSendcon is an excellent addition to any Microsoft Exchange Server, providing a practical and straightforward solution to a common issue. By distributing emails to separate SMTP smart hosts, you'll be able to customize your email routing in a way that works best for your organization.
Version 2.88: Improved: Allows slightly weird email addresses (like with _ right before the @) and omitting the <> brackets in SMTP commands.
