These are the details for the PDF password-protected file attachment received from SMTPSend OS3 sample lib. Any further help is appreciated.

  I have just been informed that SMTP send does not work with "TO Recipient" multiple email addresses with the same attachment. Has anyone found a solution to this issue? I'm working with OS10.22.

 hi Rob

I’ve used this web site in the past to check various mail server setup parameters

https://mxtoolbox.com/diagnostic.aspx

seems they only provide some of the basic test for free now, the rest are ‘upgrades'

try the basic test and see that it passes everything.  you can then decide if you want to pay for other diagnostics.

>>> Sending emails has become a complicated subject. Often a recipient of a mail will check your domain for a valid SPF record for the sender domain part of the mail. The SPF record gives a recipient information if the sending mail server is allowed to send mails from a specific domain. We have set up an SPF record on the domain bargholz.ch . If I now try to send a mail as the sender rudolf at omnis.net, the recipient will see, that the sender does not have an SPF record  that allows to send mails as omnis.net, and the recipient can reject the mail, as it thinks the sending mail server is an open relay.

If you are sending mails for your customers, they will need to add the IP address of your mail server to the SPF records in their domain, this for each of your customers. We require our customers to set up an email address on their mail server that we can use, and then send mails using their mail server using their supplied email-address. This allows us to avoid these issues.

If yes, save the file as a MSG file, then use one of the many converters to convert the mail to EML format, e.g. https://www.zamzar.com/. Have a look at the contents of the EML file in a text editor. Perhaps you can glean some information about missing parameters in the MIME list from the EML formatted mail that successfully sent your PDF.
