Setting up a BIND DNS-Server In this Tutorial we will install and configure ISC BIND 9 OpenSource DNS-Server instead of using Microsofts DNS-Server (which requires Windows Server) we use BIND 9 instead, because it simply runs on any recrent Windows version. If everything works as expected, hMailSer...

Thats correct @mattg :D But its really not a Vodoo trick,because LibreSSL is a Fork of OpenSSL 1.0.2.x which hMailServer uses normally. The main reason why i focus on LibreSSL is because OpenSSL 1.0.2.x has reached EOL and there will be no security Updates after December 2019. On the other Hand Open...

Thank you for this tutorial. It's something I've been considering for a while but haven't done much research about. 1) what is the real world impact on performance? I'm running hmail on win 10 pro on a very basic machine. Definitely not a high performance computer. 2) is it advisable to encrypt if ...

I have tested this feature, its says "its not avaiable at this time" even for formatted Windows System Partitions and even if you have only a C: Drive and encrypt the whole C:\ Drive with Windows and everything on it.

Dravion

Yeah, they are serious :D By the way, its true. The VeraCrypt Q:\ doesnt comes up automatically until By the way, its true, that a Password protected Windows user prevents hMailServer service from starting because the Q:\ drive isnt ready.

Good write up thanks Dravion thx^^ Also, the data directory and database directory used by hMailserver can be changed in the hmailserver.ini You could set these to the VeraCrypt folders, but you may need to check user permissions for this folder for the user that runs the hMailserver service This i...

Hi Kati, The Automounter mounts the Container automatically upon Systemstart without Userinput (via Keyfile) and its works with hMailServer if no Windows Password is set or a specific Windows User uses Autologon.

Hmm, i read the logs and Jimmies and Matts comments.

Maybe it has todo with your two Networkcards in your hM...

@Matt Thats correct, but no guantee MSQL server doesnt downgrade the connection. I recomnend the following steps: 1) Follow your instructions above 2) Set"Enforce encryption" to "true" (In SQL-Server Configmanager, Networking) 3)Restrict Systemwide TLS 1.2 usage (Using the NARTAC Utility for this ta...

Dravion

Take a look on the last post and use the Narca utility to restrict Windows System wide TLS 1.2 which also effects SQL-Server TLS settings.

You need to installl the latest Microsoft Native Client which supports TLS 1.2 and not only enabling in the Serversettings.

Dravion

STARTTLS is something weird IMHO. In practical programming its just a few lines of code which simply checks if TLS/SSL is possible and if yes, enabling it. Some Apps are ok with it but a lot of Apps are not which leads us to run Serverside as deprecated marked ports like 465 TLS/SSL while port 587 d...

Dravion

Nope That was solely about hmailserver versions 5.0>5.3 being closed source Ok, that make sense. How ever, we need a CE replacement DB and i think its difficult to support a dramatically down stripped MySQL 8 and later version for 32 and 64-Installers. SQLLite on the other hand is extremely minimal...

In general, you can only adjust hMailServer to use a IPv4 /ipv6 Address which is assigned to one of your Windows Network Connections or the local Loopback Device. If you setup ip 0.0.0.0 hMailServer will listen on all locally assigned ip's for each Windows Network connection but you cannot setup a i...

For running a SMTP-Server like hMailServer you need specific skills, regarding TCP/IP Networks to get things done. 1) You need a bit of knowlege about TCP/IP Network (what is a Static IP or a danymic via DHCP assigned one, what is a DHCP lease, ect) 2) You need to know, if you have a Static public I...

If you installed IIS (Internet Informationserver)
it is possible you installed Microsoft own SMTP-Service as well.

1) Goto Windows Systemsettings software
2) Check under optional features IIS
3) Uncheck SMTP Server and click ok

Run hMailServer Setup again.

Dravion

You need a local DNS-Server, setup a DNS-Domain, add a MX Entry which points to a DNS A entry which reflects your hMailServer IP-Address.

You also can use you local ip adress, your localhost or local hostname to connect with Thunderbird.In this case you cannoz rely on the Automatic sttings.

Your best bet by encrypting the SQL-Database and the Data Folder transparently is by using Microsoft own Harddisk Encryption tool Bitlocke.Its avaibe in Win 10 Pro and Server 2016 but not in Win 10 Home.

Thats not a hMailServer problem. You need to setup traffic rerouting so your VMWare Guests can accept the VMWare Hosts connections inside the Guest. IMHO: This scenario makes no sense.

Ok, if the MS SMTP-Server isnt avaiable on Win10 you can of course use hMailServer for your task.
