This section contains a list of frequently asked questions that we have received from our users. Please check here if you have some concerns or questions regarding installation and operation of quickSMTP. If you cannot find answers here, please feel free to contact us to clarify your doubts.

Is quickSMTP free for use?

Yes, quickSMTP is freeware and you are free to use it for whatever purposes, including commercial ones. As a freeware it comes with no warranty of any kind.

What do I need to run it?

A computer, running Windows (preferably version 7 or newer) with at least 2GB of memory, 20MB of storage space for program's files and as much space as your mail volume would consume. Microsoft's .NET framework 4.5 is required, and it will be installed automatically for you.

For what purposes can I utilize quickSMTP?

quickSMTP is a fully functional mail server. It can be used as home mail server for you and your family, or as a corporate mail server for a small organization. It can deliver mails by itself or it can also be configured to use a relay parent server. The number of domains and mailboxes is unlimited, which means that only your system's resources might impose any limitation.

How can I secure my email communication?

As of version 0.1, you have the possibility to run SSL SMTP and POP3 servers, which means that communication between your server and your clients will be encrypted and secured, and will not be possible to be intercepted by third parties.

Installation attempts to install .NET framework, but i don't want it?

We're really sorry to disappoint you, but without the .NET framework there is no way to use quickSMTP. However keep in mind that many other apps relay on this framework, so sooner or later you will need to install it.
