[RESOLVED] Outgoing Mail Client with VB6

Ok, another one where I'm outside of my strong suits.

And, I've done a bit of searching and haven't found anything that exactly meets my needs (although I'll keep searching).

Ok, here's the situation:

I've got a Synology NAS box, and I've just spent the last couple of days getting a mail server going on it. There's also a mail client that works through web pages, but I haven't looked into how that works at all, but it works.

I've also got a domain name registered for this email server. Right now, I'm just using the address admin@[domainname].org and it's working.''

Also, just FYI, I've got a static IP address, had it for years.

And more FYI, this is all for my wife who is a university professor involved in nursing research. She's currently studying the effects of care for Covid patients on nurses' well being.

She's got a couple of large email lists and has asked me to help getting out a bulk email, so she can administer a small questionnaire to willing nurse participants. And, as you probably know, most typical mail servers don't like sending out these bulk emails.

------

So, here I am setting up a mail server, which seems to be going well.

And, here's the question. The little Synology mail client doesn't have any "bulk" capabilities (at least not that I've found). So, I'd like to write this in VB6.

So, just an outgoing mail client. Obviously, the mail server uses SMTP for this, but I'm just not familiar with how a mail client would interface with a mail server.

Any help, or links, would be greatly appreciated.

Thanks,
Elroy
