A Linux version of hMailServer wont harm hMailServer on Windows. In fact: The HCD Project supports Windows, Linux, Mac and UNIX (Solaris) 64-Bit. The Main reason for Linux is to have a valid option to move on if Microsoft does some crap (Updates crashing Windows 10, or uinstalling Software ect) and ...

Dravions project is well meaning but still requires contributors. Thats why i want to port hMailServer to Linux because most OpenSource Enthusiasts and Coders can be found on Linux. Most of them dont like Windows but are willing to contribute if we have a Linux port running. Unfortently VBScript on...

Unknown Error at loading a EML Message file isnt verry detailed. Could be a Filesystem ord Harddisk issue, a faulty RAM Module or a interfering process like AV-Software.

Maybe not using my native language, does not understand this thread well. How has HMailserver changed in recent years? From my point of view, I have been using it for 8 years and it has fulfilled all my expectations, I have used other "paid" mail servers and the truth is that they have not made thi...

Maybe you just shouldnt save your hMailServer Data files into a Clouddrive folder....

hMailServer has some Problems, so far this is true but if you compare it to other MTAs and MDA Projecs t it has some verry unique characteristics other Email Solution cannot provide. Native Windows Support 32/64-Bit There are verry few OpenSource Email Servers for Windows out there. Even with Cygwin...

I dont know if this is a good idea regarding stability.
As far as i know Rdvh doesnt rebase its changes upto the latest official 5.7.0 Source Code base.

As far as i know he doesnt publisch his modified Source code onto his Github Account on a regular basis, so that would be a shostopper to.

Dravion

No, it doesnt inzegrate Subonhelo! Thats Rdvh Custom Project and 32-Bit only while LTS Releases are allways 64-Bit only. PS: Read the LTS MSSQL requirements carefully, you need to install MSODBC v18 x64 Driver before installing LTS because it enforces Transportlayer Security to MS-SQL Server 2008-> ...

There are multiple variants to get your Certchain working. 1) Combine your SSL-Cert with Root or Intermediate CA Cert (a SSL Certbundle). 2) Use a SSL Certstore -(a folder with all Trusted Root CAs) 3) Or have an openssl.cnf while which points to valid Root CA or Intermediate CA Certificate.

Thats not a Problem. hMailServer will HCD run on: Windows 7/8/10 and Server 2008 / 2012/ 2016 / 2019 64-Bit (AMD64) Linux / with or with X11 (Recent Kernel and Libc required) 64-Bit (AMD64) MacOS and MacOS-Server 64-Bit (AMD64) 10.10+ UNIX: Solaris 11.4+ and OpenBSD 6.5 on 64-Bit (AMD64) This goes f...

Yes, its true :) We have forked official hMailServer into a new Project called hMailServer HCD (Hmail Server Community Developer) repo which works on POSIX (which means Linux, MacOS and standard UNIX-Support) You can take a sneak peek on our Github page, but right now a heavy rewrite is underway htt...

Ok, do the following. 1) Stop hMailServer Service 2) Goto C:\Program Files (x86)\hMailServer\Logs and delete (or backup first) and delete all logfiles 3) Start hMailServer again 4) Take a look at C:\Program Files (x86)\hMailServer\Logs and put all files into a ZIP Archive 5) Attache the ZIP Archive ...

Thats because any TCP or UDP Socket Program entering the LISTENING State after the threeway Handshake is a possible victim to DOS and DDOS. It doesnt matter if the Server is called Filezilla FTP-Server, hMailServer, Apache2 HTTP-Server ect. Thats why Server Software should be coded verry carefully, ...

You are right. Last sign,of live from Martin was on Github regarding a potential Security issue last Year. The last change he made was July 2018.

Cool, good Job! Maybe you can try to SQL insert a createdate in the future first and nexttrydate a bit longer than createdate?

And what about references to such messages in 'hm_message_metadata'?

Can be ignored in this case.
The Log Errors will only triggered by the Master Record.

Dravion

I think it all comes down to the DB-Field "messagenexttrytime" for delaying outgoing mails. UPDATE `hmailserver`.`hm_messages` SET messagenexttrytime = '2019-05-10 08:03:59' WHERE messagefilename = '{C6C3D5C8-8820-4BE0-923B-CD4C02708AD8}.eml'; If you run it via COM API Database Object, you can trigg...

Dravion

You also can stop hMailServer, login into your DB and delete the orphaned DB Records yourself

For example like this:

DELETE FROM
'hmailserver'.'hm_messages'
WHERE
messagefilename like '{8F79335E-A0A3-4B0A-9099-6F802E6737D0}.eml'

After this, restart hMailServer, the Error should be gone.

Dravion

Why did you do this?
If you simply overinstall it about your existing Installation all DB Data would still be in a correct state.

Now you need to extract your old DBSettings and insert it into your new DB.

There is something strange going on. In the Repo on Github Martin has added SQL-CE Compact 4.0 SP1 but the Installer packages Microsoft SQL Server Compact 3.5 (32-Bit Version only) which will trigger a Incompatibility Warning on Windows 10 64-Bit. For the official 5.6.7 Build 2425 (32-Bit Release) y...

Dravion

Thats completely reasonable because you need Microsoft SQL Server Compact 4.0 SP1 x64 ENU You can download the same MS-SQL-CE Runtime the hMailServer Installer will install from the official hMailServer Developer Repo (click the Download Button) https://github.com/hmailserver/hmailserver/blob/master...

Dravion

For hMailServer 32-Bit you neeed the x86 Version, for hMailServer 64-Bit you need the x64 Version.

After installation restart hMailServer Service and try to login with hMailAdmin. If you get an Error, post the Error text into your next reply..

Thats because of the Nature of a SYN Attack. SYN Cookie is sent to the TCP/IP Stack of Windows, pretending the incomning Attackerwants to establish a connection but before the Connection can be established the Attacker disconnect.

In most cases its a Scriptkiddy trying out Systematically all pingable ip addresses.

If its stupid scriptkid, just block his ip and you are good to go.

Dravion

That looks like a SYN Flood Attack to me. Its a verry old type of Attack and any decent Firewall Appliance and even the Linux Standard Firewall can dodge such packets easily. I recommend to enable SYN-Flood, SYN-Cookie Attack defense Rules in your Firewall Appliance in front of hMailServer. Even blo...

As i saod, its more complex than a Antivirus Program. hMailServer is trying to handle a Task which it cannot finish in a specefic time Limit. This can be a total Random task but experience shos its mostly a SMTP task, trying to sent an Email to a diffrent, thirdparty Emailserver. If you use a Thirdp...

The advantage of the 64-Bit version is, it cam access Memory beyond 2 GBytes. Theoretically it can scale up to 8 Terrabyte RAM.

Dravion

in detail its a bit more complicated the just a Networking interference with Thitdparty Software like fotrexample Antivirus Programs.

Its a Task which cannot be completed by hMailServer in a timely fashion.

Ok, but that doesn't explain why the OnClientConnect event was ignored. OnClientConnect is nothing what comes from official hMailServer code. It must been inserted by RdvH.
