My advice was made under the assumption that you have a Microsoft Office365 Account + Exchange Online option and that YOU want to sent Emails from your local hMailServer to a Office365 Exchange Online Account and let Office365 deliver your Emails (a Relay server configuration). But now it sounds lik...

Dravion

You need a Office365 Account which includes "Exchange Online". In Exchange Online, you can configure your Mail flow Receive connector. The outgoing hMailServer SMTPD Relay Request has to be TLSv1.2 and the used SSL-Cerntificate needs to match the same Common Name in the SSL-Certificate than your Exc...

What is this?

2684 "debug" 5764 "2019-12-24 09:39:57.507" "executing event onacceptmessage"

There is something triggered after the Email in question was already received.

The best would be Postgres. From a Development point of view its best to upgrade and best to support. It also supports TLSv1 2. There is no Light or costly Enterprise Edition and its very stable. Right now 9.x. /10.x is supported but 11.x and 12.x is easy to integrate just by recompiling hMS with ne...

Staying secure is always a run between a Rabbit and a hedgehog.

If you fall short with applying patches, you risking your complete hMailServer.
Its more likely to get hit by a hack if you run on a unsupported OS than not because
the old security holes will never get fixed.

Dravion

There is indeed an attack possibility by injecting malicious code into an Email. But to trigger such a flaw and taking advantage of it, you need a lot of experience and detailed info about the peace of Software you want attack. IMHO hMail marketshare is to small so it doesn't make a lot of sense to ...

Disabling all the rules made no difference to the CPU usage which leaps 34% until it consumes 100% in anything from 45 mins to several hours.

Thanks for the help anyway. A thought - I have over 6000 rule criteria across 100 rules.

Just for clarification. Do you run any VBScript or DCOM API accessing Scripts or Apps as your CPU usage spikes up? Do you use SSDs or normal Harddrives? Is your Server running on a public ip address?

Ok, Problem solved

Dravion

Okay,

ReRun SFC /scannow again and see if now any Error is fixed.
Sometimes SFC doesn't repair anything. If it comes back with more Error, please report back
and make sure you have your Windows Server 2012 R2 Original DVD or USB Stick ready and inserted for the next
step.

I still don't understand why there is ODBC driver involved

That's not normal for hMailserver is it?

The hMailServer Database Manager uses ODBC for example MS-SQL-Server or MS-OLE DB Provider for accessing MS-SQL-CE. Its not needed by MySQL or PistgreSQL.

This is not a IP SQL Insert Error.
It's an Timestamp insert error.
I assume you are in the German, central European Time Zone (CET) and Palinka doesn't check the correct Timestamp format for any location of the World. The Format might be differen't in it's Home location.

You realy should reset your Windows Update cache first (this will not harm any installed updates) so Windows can repair the Update System if it has any Errors itself.

Only make sure you run SQL via hMailServers DCOM Object and not with a direct db access tool, so hMail can delete all *.eml file dependencies as well ir you have Millions of orphaned fragments you need to check manually later.

In any case, you should upgrade to MySQL, PostgreSQL or Microsoft SQL Server if you are care about Support for Databases in General.

If possible, run Wireshark in cases where incomning connections are timing out, logged by hMailServer, stop
Wireshark and attach your resulting Wireshark *.pcap log file as a zipped archive in your next reply. I will take a look into it.

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.
