You need the 32-Bit variant of libmysql.dll v5.7.30
and you need MySQL 8.x to allow legacy Connection.

Dravion

Change it after Installation:

In hMailServer.INI

[Database]
Port=1234

I think I 've had a couple of machines do that update automatically this week, as I've noticed the 'use your microsoft account to sign in' window on a couple of machines that have updated.

Don't remember a 5GB download though. Is that a complete install disk?

Yes.

I checked it out.
Its basicly a frame App which encapsulates Powershell and CMD.EXE. A nice feature are tabs thats it in a nutshell.

I tested the next big System upgrade for Windows 10, which comes down the next few Days for all Windows 10 Devices, except if you paused or disabled Windows Updates.

Does do you hMailServer to bind to the SSL certificate generated by Win Acme V2? It seems to generate a new certificate filename each time it renews the domain.

The information provided allows the following assessment: You said, its happening while you trying to send an Email, so this is an SMTP-Protocol operation on port 465 SSL/TLS or Port 587 STARTTLS or without encryption. But this is irrelevant, because the connection was successfully created between y...

The Error is a Client side triggered event. However, this can also be triggered by a interference of some sort of a third party program on your hMailServer Computer, like a Antivirus Program on your hMailServer\DATA folder.

It looks like you are behind a NAT-Router, which is connected to the Public Internet. Your Local Network ip address is obviously auto configured by your NAT-Router (to a 24-Bit Subnet like this: 192.168.x.y) Problem is, your Subnet is only known to our local Office/Company/House Local Network but no...

You can define a Relay server Host by ip address or hostname.

It's up to the Relay server to handle, reject and deploy the inbound Emails.

Dravion

The Problem is what it says: Out of Memory, which means the Address space (which can max 2 GBytes of Memory) is to small for your Setup. There is no final x64 Version, but you can use my custom build which has at least a OpenSSL 1.1.x version included. https://www.hmailserver.com/forum/viewtopic.php...

Dravion

Install a 64-Bit build of hMailServer to avoid out of Memory Situations.

Dravion

Ok, a few things you can checkout. AccessViolations (like you are facing with your hMailServer Installation) is indeed a Memory Problem, but there are chances this is not only a Software Problem. In fact, we see a lot of freshly, new installed Servers which are running on faulty Memory or buggy Driv...

Data Execution Prevention (DEP) addresses a different Problem.

Dravion

No, HCD isn't any longer in development, because it would result in a complete different development direction which wasn't my plan.

Dravion

You need to enable the Debug settings in hMailAdmin to get detailed logs.

If you don't use a DNS-Server, you need to append your ip address instead of your DNS-Domain name after the user account @.

Like this: joe@192.168.1.1

Dravion

Username is: your_hmailserver_emailaddress@yourdomain.com

TB shows up Password dialog until any params are correctly setup.

Try telnetting your hMailServer ports and take a look in hMailServer log files.

The Server is written in C/C++ (unmanaged/native)

Only the Client tools like hMailAdmin and DBSetup are written in C# (targeting old .NET 2.0).

Dravion

Wine can do a lot of cool tricks but .NET Framework stuff doesnt work well on top off it. hMailServer needs .NET for Setup and hMailServer Admin. On Linux you should consider running a mature and stable Solution like Postfix+Dovecot for services like SMTP/POP3 and IMAP. Sorry to revive an old threa...

Yeah, I figured the GetARecords error was just an MX-related error. I'm not too worried about that one, as I can track down which list those are coming from. Any other thoughts regarding the Task-DeliveryTask crash that I still have going? Yeah but first you need to preset your latest log entries (...

Dravion

I had to give it a few days, to make sure all regular retries were cleared out. Once they were, I cleared all of the failed messages from the queue, made sure there were no emails in the Data directory, and restarted the service. Once new emails started going out today, the same service crash start...

Dravion

This is correct.

But you can setup multiple ip ranges which will allow authentication for some ip addresses or ranges of ip addresses or even on a single ip address,
so you should get what you want with this method.

Connection security/Certificate is controlled per port.

Connection security is done by activating SSL/TLS by setting up a SSL-Certificate and ports has nothing to do with Connection security.

Ok, it took a look inside of it. From a Development point of view, this is a Windows Memory Access Problem. hMailServer is trying to read specific data from a location which it doesn't has granted permission to it. In Programmers terms, its a pointer running wild. If something like this occurs windo...

Dravion

Regarding firewall, you don't have special needs if your hMailServer is running within your Local Area Network in your Office and fetching and delivery Emails against or from a SMTP-Relay server / Smart host. Firewall on hMailServer makes sense if you have a Dedicated or VPS-Server at some Webhostin...

Dravion

This is a hmailserver.exe System Service crash.

The new Minidump cannot be written because you have a lot of them already in your log Directory.
Clear your hMailServer log folder and if this happen again, attach a new Minidump file to your next reply.

The AVG Firewall in its current version has a problem, executing custom filtering rules correctly. Anyway, you can disable the AVG Enhanced Firewall feature so you automatically fallback to the normal Windows 10 Defender built-in Firewall which allows the same filtering options than AVG Firewall (bo...

Be patient.
Maybe its Graylisting.
It can take up to 72 hours before a new domain is seen as valid for deployment (new in terms of a SMTP-Server).
