Hmm Fast io disallowed looks like another part of the Problem, which is caused by the faulty Windows Update. hMailServer uses the BOOST C++ Framework and espacialy its Async IO Component ASIO. On Windows ASIO needs a functioning I/O Completion port to reliable adjust hMailServers File, Networking an...

What SQL DB do you use and what about the "hMail" ODBC Alias in your logs?

MX Records are set at DNS Level.
You can set as many MX Records you want
and set a threshold TTL for any MX.

Normally the first MX is set to TTL 10, the next to 20
and so in. If MX with TTL 10 doesnt react on threshold than MX TTL 20 is contacted ect.

Ok, will look into it if i have time

If your ASP.NET C# Script is running on your hMailServer computer, you should try 127.0.0.1 and Port 25 instead 185.164.72.225 and Port 25. Make sure your Hosting provider allows Port 25 SMTP Mail exchanges. In many cases, port 25 is blocked for vServer or Dedicated Root servers. Contact your Hoster...

It doesn't matter if transport is done via SMTP POP3 or IMAP. The final result is always a *.eml file inside your hMailServer DATA Folder. In you case you need to put a *.eml file to the location where hMailServer is trying to fetch via POP3 to make the error go away. Afterwards you can delete the f...

My company operated HMS behind a standard router (with whatever the usual firewall protections that provides) and windows firewall - and worked PERFECTLY fine.

Something worked NOT perfectly because your boss decided to get rid of your hMailServer Installation and replaced it with
something else.

Dravion

No. MX Records are set by a DNS-Server (in most cases ISC BIND9, which is the defacto standard for DNS) and your Domainprovider has as best a simplified config page where you can set such entries but the underlying DNS-Server is still BIND9. In this case you use your Domain providers Hosted DNS-Serv...

This is not a hMailServer Problem, its a MySQL Problem.

By the way, why dont you install MySQL on the NAS or a different Computer on your local Network?

hMailServer can handle MySQL Databases,installed on a different Computer.

Dravion

You need allways a port 25 per Domain so hMailServer can exchange Emails with other SMTP Servers on the Internet. Port 587 or 465 is for Email Clients like Thunderbird only.

Its all happening inside the DATA Folder.

Check your RAM Memory with Memtest86+

"Bad allocation" is a Memory Module Hardware Error.

It can occur but it only pop's up if the faulty Memory cell in you RAM Chip is accessed
by Windows.

There is no other Solution than replacing your faulty RAM Modules.

Thanks Dravion, I have done that too and doesn't work.

"Fatal error: Uncaught Error: Class 'COM' not found

Without PHPWebAdmin cannot work.

Dravion

In your log, it clearly says "bad certificate".

Thats a Error message rooted in OpenSSL's
Security Library which is used by hMailServer to handle SSL-Stuff. It means it cannot load mod_md's LE renewed
SSL-Certificate because it seens to be corrupt or is formatted in a way OpenSSL doesn't understand.

Make sure PHP loaded the Microsoft COM

In your Debug log its unclear if its a SMTP or IMAP or POP3 Session. Your Client also is trying to negiotate a SSLv3 Session which is unsecure and thats why in newer hMailServer versions SSLv3 support was removed.

In hMailServer, a PHP Script is seen (from a hMailServer perspective) as normal SMTP-Client.
