Did he only forget hMailServers Login users Password or MySQL Root Password to?

If MySQL Root password is avaiable, login with MySQL Workbench via Root user should be ok.

But if hMailServer is conbecting via MySQL Root user + its Password its a diffrent story...

@MattG

Yeah, there are multiple errors in the log. The cannot read text file is of course Storage related.

Maybe copying the DATA folder to the hMailServer Computer and letting hMailServer.ini pointing to it could solve the Problem.

Dravion

hMailServer can logon to your MySQL Database Server, thats not the Problem. Its also not a access or permission Problem. It seems to be a Problem at updating a Date value because a received Email has a wrong or malformed or null Dateformat which results in a rejected SQL Update query. I think, logon...

Try to enable Exchange log settings
so you can see if hMailServer is trying to fetch Exchange IMAP and POP3 Inboxes.

Check espacially errorprone logon attemps on Exchangesite.

Test if Exchange POP3 and IMAP Ports are open and
accessible by telnet.

Dravion

Ok, this is really getting weird. Can you update to a Win10 or Windowd Server 2016 Version? I also had a Customer where Hardware was ok but there where Micropeaks in the Powergrid which caused some Problems. We solved it by setting up a UPS and plugged it into the Server and connecting the UPS to th...

Thunderbird has a long History of STARTTLS Problems for Port 993 and 995. This seems to be fixed in version 60+. As workarround SMTP and IMAP/POP3 Serveradmins used STARTTLS Required on IMAP unencrypted Port 143 and unencrypted POP3 with STARTTLS Required. Its more a Workarround for Broken-Clients. ...

It will replace hMailServer files, which are allready exist. Its recommended to just backup your old hMailServer Folder so you can switch back if something goes wrong anytime. Make sure you copy your old hMailServer.ini file to a safe place because this MSI Installer will overwrite your old hMailSer...

Follow this Firewall Tutorial, it should do the trick

Youre rught.

The more traffic, the more your pay

Dravion

Yeah, some Systems want it because RapidSSL depends on Digicert but IS NOT Digicert.

If you had a real Digicert Certificate you dont have to care about the chain of trust and merging it into a bundle at all.

Dravion

The thing with Intermediate Certificates is allways the same. Some cheap new SSL CA is licensing the usage of a well known Root CA and acts as Intermediate CA Authority but such a Intermmediate CA is never independent. I recommend not to use such cheap SSL Certificates because you have to fiddle out...

Dravion

Regardless where you get your new Certificate or even if you selfsign it, its allways a x509 Certificate which will in most cases come as *.crt *.key pair bundle. Its even possible to copy and paste it and it will work.Of course, there are other formats like MS PFX or SPC, DER or P12 but thats not c...

Is support of encryption in my version as simple as purchasing a certificate, pointing config to cert & key, and enabling SSL on ports?
I want Outlook clients and RoundCube to connect securely so passwords/mails won't be so easy to snoop via wifi etc.

Yes.

Dravion

The Company where you purchased your SSL-Certificate isnt supported anymore. You need to buy a new SSL-Certificate from a well known CA like DigiCert or Verisign or you can use a free 90 Days renewable SSL-Certificate from Letsencrypt. Check our Tutorial Section, there are some Guides for Letsencryp...

Dravion

STARTLS isnt really a encryption.

Its more like:

*Client logs on to server (unencrpted)
*Check if the Server respomds with STARTLS
*If yes, upgrading to SSL/TLS

So, STARTTLS is short and simple SSL/TLS
behind the curtains.

Ok, why in the World need we another Scripting Language?

Hi, Sorry, it took longer as expected. My first idea getting this Problem solved wasnt sufficient and seems not a good idea in itself. The only thing left is, to get to the bottom of this Problem and trying to fix it by sanitizing the inputbuffer before a Error can happen. This is a tedious Job and ...

Ok thank you Dravion for support,

i can debug HM operation and post log file.

This will be helpfull.
Make sure you enabled all the checkboxes in hMailAdmin for logging, so we get a very detailed logfiles.

Dravion

Good Job.
Yeah, MTU Stuff can be verry nasty.

I had it a few years back. Firefox wasnt able to send any HTML Formular and took forever. After incrementing the MTU value, it was gone.

I filed this as official bug on the hMailServer Github Issue page

See:

The Crashdump didnt provice much more Information then we allready know.

Yeah, the Function in question parseData exists in allmost the same form for SMTP/POP3 and IMAP.

Dravion

I still think that the local machine AV is quarantining the .eml at this point in time as the Data Directory hasn't been excluded from AV scanning. If the email contians a virus, the AV won't allow that virus to be written to disk Thats unlikely because hMailServer doesnt save the variable to Disk ...

Dravion

You have an SSL Error for Port 995 and Port 995 is encrypted POP3

You dont need to look for Port 110 if your Problem is 995

Dravion

In hMailAdmin, you can setup a new Administrator password.

If your Pop3 SSL certificates has trouble,
delete it from the SSL-Section in hMailadmin
and set it up new, a reasign it to,port 110.

Dravion

@PeterChan

You need Port 25 AND Port 587 set as SMTP

BOTH Not Port 25 SMTP OR Port 587 SMTP

You need both ports 25 and 587!

Take a look at my Screenshot and you can see what i mean.

Dravion

Where is your port 25?

No Emailserver can work without a Port 25!

Dravion

The MSI requires .NET 4.0 or higher because the Client Tools where updated to 4.0.If the MSI installer doesnt find it, it will inform you to install a .NET 4.x Version and quits.

ps: It also uses LibreSSL instead of OpenSSL

If you want OpenSSL, use the above mentioned Classic-Installer.

Classic Installer with updated OpenSSL Version and included libmysql.dll can allways be found here: https://github.com/hMailServer-ComDevs/hmailserver/releases Experimental, new MSI Installer can be found here: https://github.com/hMailServer-ComDevs/builds/releases Remember, this is x64 only.

Timeouts of the Remote Party means, the connection is unstable or willfully rejected (mostly by Firewall of the Remotesystem).

My thing Dravion, is that I think that the certificate they are using isn't working correctly, and I was trying to point them to get hMailserver working without a certificate to see if that fixed the issue in the original post.

Of cause! Abd you need it both ways (InBound and OutBound) For example: If you only enable InBound, Client Apps can connect but no payload bytes from the server side will reach the connected client. So, to ha a real open port, make sure its InBound 587 and OutBound 587 The same goes for Port 25/143 ...

Dravion

587 is best for IMAP-Clients like Thunderbird (StartTLS) wihle 465 (SSL/TLS) works best for MS-Outlook and Windows Mail App or any other Windows Crypting accessing Email Client (like EMClient or Mailbird for example).
