Hi, I want to know what it does do, per below log details? "DEBUG" 3820 "2019-06-27 09:07:47.898" "Creating session 397" "TCPIP" 3820 "2019-06-27 09:07:47.906" "TCP - 3.94.116.70 connected to 113.255.213.124:25." "DEBUG" 3820 "2019-06-27 09:07:47.914" "TCP connection started for session 396" "SMTPD"...

On below URL

http://hmailserver.com/forum/viewtopic.php?f=9&t=34082

it is done for MYSQL database. Does it mean we can re-write it for MSSQL, right?

Good day Mattg,
How to ban one IP from "approaching" our server?

PeterChan

Mattg,
Thanks a lot!
How to force all connections to ONLY use TLSv1.2 when the connection is secured?

PeterChan

Mattg,
Thanks a lot!
How would it be easy to totally block their try from "checking/validating (or attempting to steal)" against the server? Did you ever succeed in doing this?

PeterChan

Thanks a lot!
What is the purpose of the relevant party, who ridiculously are repeatedly running jobs for doing such "BAD" routines? Does it mean they're trying to steal any "potential" resources for doing their jobs?

PeterChan

Thanks a lot!
It means IP 185.222.211.13 is repeatedly annoying my server, by giving "rubbish" commands, right?

PeterChan

Can you tell me meaning of "RECEIVED: RCPT TO:<offers@a.co>", to the below? "DEBUG" 3772 "2019-06-21 11:42:57.870" "AWStats::LogDeliveryFailure" "SMTPD" 3772 41 "2019-06-21 11:42:57.870" "185.222.211.13" "SENT: 550 Unknown user" "SMTPD" 3812 41 "2019-06-21 11:42:57.870" "185.222.211.13" "RECEIVED: R...

PeterChan

Thanks. All 550 events are rejections, right?

Hi, It is currently bad to find out that other people were making use of my domain to send out messages like 2019-06-20 17:03:17 3n899f3lvn2en@artist-oil.ru lucas@a.co 185.222.211.13 127.0.0.1 SMTP ? 550 0 2019-06-20 17:03:17 3n899f3lvn2en@artist-oil.ru beth@a.co 185.222.211.13 127.0.0.1 SMTP ? 550 ...

PeterChan

Hi,
Can you share one exact format for SPF record to be used by the domain?

PeterChan

It is now fine to send out messages. Before this, it was also fine to send out messages.

PeterChan

Hi,
There is only one line like

127.0.0.1 smtp.SearchHouseLive.com

I tried to stop the action of spammers and how to identify reason of issue below?

PeterChan

Sorry, I do not see your screenshot.

Any example to have 2 ports together, for SMTP.

PeterChan

Here is what I get 220 WIN-APIUFD1NJEU ESMTP after having put Telnet smtp.searchhouselive.Com 25 to hosts file. Here is what I've got in Diagnostics Test: Collect server details hMailServer version: hMailServer 5.6.7-B2425 Database type: MSSQL Test: Test IPv6 IPv6 support is available in operating s...

Sorry, how to get INTERNAL DIAGNOSTICS?

Here are some log details

Thanks. Here are what I've got C:\Users\Administrator>Nslookup smtp.searchhouselive.Com Server: localhost Address: 127.0.0.1 *** localhost can't find smtp.searchhouselive.Com: Non-existent domain C:\Users\Administrator>Telnet smtp.searchhouselive.Com 25 Connecting To smtp.searchhouselive.Com...Could...

PeterChan

Sorry to that, I changed SMTP port to 25, like

but I still have got the same issue.

PeterChan

Dravion,
I did already assign it below

Mattg,
I can only see the current log details below.
https://1drv.ms/t/s!Ai8CrEskdewXnEToVFlN22dlJtEv

PeterChan

With these setup now

I am still getting issue

PeterChan

I do put the correct AD account and password and do not know why I've got the below error

PeterChan

I followed your advice and any advice to this?

PeterChan

Here is problem

PeterChan

I bought relevant imap and smtp certificates and have applied them like

but I get below problem. Why?

PeterChan

Suppose I would get certificate, would it then be fine to use the below ports? 0.0.0.0 / 465 / SMTP - SSL/TLS Cert: xxxxxxxx.com 0.0.0.0 / 993 / IMAP - SSL/TLS Cert: xxxxxxxx.com 0.0.0.0 / 995 / POP3 - SSL/TLS Cert: xxxxxxxx.com

PeterChan

Thanks to all.
Dravion,
Does it mean there should be 2 separate certificates, respectively for imap.domain.com and smtp.domain.com?

Including the certificate for the below, there would be 3 certificates?

PeterChan

If I use Thunderbird (and suppose to use 587), I should enable TCP port on 587, right?

PeterChan

Should I use 587 or 465 (instead of 25) to SMTP?

PeterChan

Hi,
Confirm fine to send out message but now problem is that I cannot receive message properly. Here are some current log details

https://1drv.ms/t/s!Ai8CrEskdewXnEILzKoCIUDmSF1c

PeterChan

Yes, I've applied the changes and do not know why problem appeared.

PeterChan

For about 1 and half year.

Here is the setup I've already applied

PeterChan

I adjusted the ports per your advice and have saved the change but now I have got this

PeterChan

How to remove security from ports?
The certificate was verify by Namecheap.com that it was fine.

PeterChan

Since I expect to further work with certificate, what to adjust to resolve problem?

PeterChan

I get the certificate from namecheap.com.

PeterChan

Thanks to all.
Jim,
Where to adjust? I do not use FQDN.

Katip,
It does repeatedly prompt for password, while I've entered AD password correctly.

Mattq,
Previously, it was working to send & receive mail, without SSL certificate.

PeterChan

Jim,
Thanks a lot!

PeterChan

Hi,
FYI

PeterChan

Thanks to all.
Mattg,

Below, Huamin2 is one existing AD account on domain SearchHouseLive.com.
