Will adding a SMTP route fix this for you?

mattg

check the user that the hmailserver SERVICE is running under

That is probably local system account

You may need to create a special user to run hMailserver SERVICE under

mattg

So would you also recommend, as best practice, switching on SMTP authentication for local-to-external for the localhost IP range? If so, I wonder why that isn't the default setting? But it is, isn't it. the default settings are suitable for MOST use cases, and are safe for beginners - that's the po...

There is no right or wrong way to use BCC Example A FROM roadrunner@acme.co TO roadrunner@acme.co BCC tassie@acme.co, elmer@acme.co, bugs@acme.co, coyote@acme.co Is USUAL for a mailing list (but there are other reasons for using BCC other than mailing lists), and this only shows each recipient who s...

I think that the unnamed mail client doesn't respond correctly to the IMAP capability statement sent by hMailserver If this works with other mail clients, I'd suggest that the 'un-named mail client is broken' Perhaps Wireshark will provide more detail, but it simply looks like the mail client just e...

But what if there is no 'return-path'??

mattg

User name is 'administrator', and password used for the admin GUI

OR

You can use any email address, and the matching email password, but then you get a cut down version of PHPWebAdmin, depending on your user role and permissions. Ie a domain admin can manage only their own domain

Can you please show the next 90 seconds of logging in it's entirety You showing us what you think is import isn't enough.

The create new header requires scripting, but either option 2 or 3 would do as for your needs....

Use an SMTP relayer to send ALL messages via a particular relay
For just your own domain you could use a SMTP route

hmailserver will only split sending if the addressees are different domains (or are BCC recipients)

mattg

you can instead use routes, and have a global rule call a route

What router / firewall device do you have if any, some of them do SMTP inspection

(Perhaps just flagged as 'no local account matches')

mattg

You would need to script the removal of .doc files and stop mail for your domain using that function

'self signed certificate on the server' might be the problem

In your mail client (outlook or thunderbird) check for a 'security' window in the background that wants you to accept the certificate

mattg

clearly the logs says

Code: Select all

An established connection was aborted by the software in your host machine

That's pretty explicit

mattg

An established connection was aborted by the software in your host machine

Some OTHER software on the machine with hMailserver installed is breaking the connection
Did you remove avast on the server, or only on the client?

mattg

specifically check if these accounts are real accounts on your server myouse@sXXXXXXXXt.com sdhar@bXXXXXXXXXa.com I suspect that they are not, and the issue is the postmaster account I'll bet that you are forwarding form one postmaster@ account to another and so on, creating a loop You have the post...

What Antivirus do you have on the Windows machine?

mattg

That log looks fine

That looks like a successful connection. Are you sure that is your windows machine connecting to your hMailserver?

mattg

Any error logs created when running the 64 bit version?

mattg

That's where I've been doing it for years

Yep, route is correct If the ACCOUNT exists locally hmailserver will always deliver to local account If the DOMAIN exists locally, but NOT the ACCOUNT, then a route will see mail delivered to the external hosting of this domain.

mattg

Web server and mail server are different ports, protocols and programs serving those

It is more likely to be antivirus installed on the machine with hMailserver installed, and the antivirus will be 'inspecting' SSL mail

Going to start playing with the 64 bit version to see if we can switch it in/out in place of the 32 bit one - hopefully, the DB and file structure is the same between the two.

Yep

Backup first
But the 5.7 version should just install over the top of 5.6.X

mattg

for a start your IIS SMTP still answered during that test, so it isn't disabled

After you disable it, then run this and post the results viewtopic.php?f=20&t=30914

mattg

A new version will always be better
Security fixes and more features

Simply
BACKUP - to be safe
Then download and install new version over the top - takes only a few minutes
