COM Library for sending mails via SMTP?

[Resurrected]

Is there any utilities one can make use immediately to send emails via SMTP? Close source, or open source, doesn't matter.

Any suggestions?

vbRichClient5 has the following classes:
cRPCClientInfo, cRPCConnection, cRPCListener, cRPCListenerThread, cRPCStatusInfo, cTCPClient, cTCPServer, cUDP

I don't know if they can be used to send emails, maybe Olaf can answer this question.

If commercial libraries are acceptable, I've been using Chilkat with success: https://www.chilkatsoft.com/default.asp

There's a lot to handle with SMTP like encryption, DKIM, attachments, etc...so rolling your own would be a big job.

At work we're using the "Dart-Dlls" (former PowerTCP-COMponents) for all kind of Mailing-stuff -
they still offer bundles with COM/ActiveX-support:

I agree with jpbro, that "writing your own, based on plain winsock-APIs" would be a huge task these days (with all the SSL/TLS-stuff now involved).

But since you mentioned the RC5-(socket-based) Communication-Classes (which BTW don't support standard-Mail-protocols out of the box):

Do you plan to use Mail-Protocols only as "just another transport-vehicle"?
(to ensure "transfers to a Web-Host" in conjunction with your planned "Instant-Messenger-App").

If yes, there are far better ways to approach that.

Perhaps some of these projects can help?

Why wouldn't you just use the CDO library that Windows comes with?

There are thousands of samples out there, though some are pretty crudely done and appear to be based on very ancient ASP VBScript copy/pasting.

Also, vbSendEmail library (free with source code)

I am planning "Instant-Messenger-App" and are collecting relevant information and third-party tools. After a few weeks I will post a thread to discuss the specific solution, hoping to get your advice and help.

No, I'm not Resurrected. I have sent a thread about IM-app some time ago. I'm sorry to talk about things that are not relevant to the OP's topic.

Guys. Sorry for the late reply.

Nope. Not in this case. But I'd like to learn about the RC5-(socket-based) Communication-Classes.

Commercial libraries are not my options. I will try those mentioned above. Thanks
