Outlook is not pre-installed on any Windows product I have ever had. Maybe you are confusing Windows Mail App pre-installed on Windows 10 as being Outlook. It does resemble Outlook but it is not Outlook and a bit restricted in features compared to Outlook. Solly, when we had our computer shop XP wa...

Does pale moon allow and use old style firefox add-ons?

Not sure because I don't use them except for one that stops autoplay of video. But they do provide an extensive array of add-ons that are compatible.

Kendo

Since Firefox started adopting useless features found in advertising gimmick browsers (no name mentioned) I started losing interest. Dropping support for NPAPI, Flash and Java, plus persistent nagging about updating to their latest version of nonsense was too much in the end.

I now use Pale Moon.

Everyone's favorite is MS Outlook. Only because they find it already installed with Windows and don't bother looking for an alternative. I don't know if they have changed it much or not, but one big no-no was the way they hide the sender's email address. If anything, that should be most obvious, es...

And spammers sending mail via command prompt will be seen as Server or My Computer?

Kendo

I understand the "local" and "external" email address difference and assume that the "Internet" range is for mail sent via SMTP to my server from outside the server, but what is the significance/difference between "Server, My Computer and Internet"?

Kendo

In the settings for IP Ranges there are 3 options: - Server - My computer - Internet I assume that "Internet" means email sent via the internet using normal channel for SMTP, but what do the other 2 options mean specifically? For example a spammer sending direct via my server... will appears as a lo...

Your SPF record allows your own mail server to send emails.

Of course it does. It is also listed as an allowed IP address. How else can websites hosted on it send mail outward?

Without any SMTP Authentication settings, why doesn't SPF prevent non-authorised IP addresses as senders using local email addresses?

What exactly is the role of hMailServer in your organisation? 1. To send mail from webforms on the same server. 2. To send mail from cms on the same server... from authors to subscribers. 3. To receive mail sent to the listed domains/accounts. 4. Received mail then gets resent to a separate server ...

How do your customers send mail normally? Webmail only?

New clients use a webform on one of the websites. Some sites are on the same server and some on another (apache) server.

Established contacts email directly from their mail client.

If oMessage.Subject = "=?utf-8?B?5LyB5Lia566h55CG6LWE5paZ?=" Then

How does this detect anything that is not specifically "=?utf-8?B?5LyB5Lia566h55CG6LWE5paZ?="?

Or does the regex need to be included? If so, please provide an example of the completed script.

I believe you got your answer in the second post...

In hindsight that is easy to say, but now we know why. Perhaps hMailserver can be upgraded to cater for such a simple rule. Then we could do without SA which I have never liked.

Kendo

We already got all of that, except for those clouding the issue by posting irrelevant suggestions.

TB = Thunderbird?

That is of no use because it is the mail server applying the rule and not your local mail client.

Combine Script and Rules.

The string "=?utf-8?B?5LyB5Lia566h55CG6LWE5paZ?=" is Base64 encoded using UTF-8 charset.

The Subject is different every time, but always contains "?utf"

If the header is in Japanese, for example, the contents of the mail will not be searchable. "?" in raw view likely no more exists after decoding attempt.
