you just need to enter the smtp server of the receiver's mail provider
Ex: if you send to lala@hotmail.com
the smtp server is mx1.hotmail.com

I have already the same problem
"can not find SMTP server" occurs all the time.
firewall doesn't exist on my test-machine.

I wanna send email to my test account:
webinfo747-mfc@yahoo.de
and use smtp server: mx1.yahoo.de
any idea whats wrong?
may I choose another smtp server or,better, do you have a valid smtp server for testing your app??

thank you for help

I have rated this article a 1. Please see my reasons below.

When creating applications such as this, it's a better idea to use the MFC classes for handling threads rather than using the core Win32 API methods. The reasons for this is that it's less prone to errors in that the MFC was designed to facilitate better functioning and more programmer-friendly (readable) code.

I noticed that you make several calls to GetDlgItemText() which are all clustered together. This is confusing in that someone else reading the code can't be exactly sure what is what. If you would have implemented this in the MFC it would have been alot more clear and compartmentalized as each item in your dialogs would have had a member varible which you could use to access that item exclusively and also provide some kind of an indicator as to what is what.

You threading also seems to be a little strange in that you do absolutely no error checking internally as far as I can see. One bad message from the STMP server could totally kill your thread and lock the application. these are things that need to be factored in when you do anything like sending emails.

I would strongly suggest that you update your code to use the MFC a sit will only end up helping you in the long run.

It's good to see kids turning their minds to wholesum activities such as programming, instead of wasting their lives in the hedonistic disciplines of Sex, Drugs, & Rock & Roll... or Sex with Drugs, or Sex with Rocks while Rolling in Drugs, or whatever new-fangled perversions you little monsters have thought up now...

hi

Hi,

I'm doing a web project which requires a way to send a huge number of emails to subscribers (like a mailinglist). and this point is very important : mails must be sure to be sent.
I now write a C++ app. on Windows 2000 server, use CDONTS component to send mail. this is very convenient, but i faced a problem : CDONTS relies on SMTP service of IIS, and in pretty poor internet connection, IIS's SMTP service seems stucked for pretty long and seems not reliable.

Do you have any better solutions ? many thanks

A bit of knowledge in the wrong hands is a bad thing. Two or three messages in this thread are desiring the knowledge to create mass spam programs, and worse, mask/cloak orginating IP.

I run a successful online business and have never resorted to mass e-mailing. Mass e-mailing gives legitimate Internet businesses a bad name, and quite frankly, most people hate getting spam/junk e-mail.

Many have resorted to services like SpamCop.net to combat spammers, and ISP's have resorted to "black holes", "black lists" to ban web hosters IP blocks from accessing their nets if they are known to be a safe haven for spammers. The ISP's who allow spamming in order to get web hosting dollars are identified as well, and some legal/court battles have taken place.

As a result, many ISP's now prevent mass e-mailing on POP/SMTP accounts. This has hurt legitimate businesses who e-publish newsletters that clients have paid for in that their e-mails are blocked and the customer complains of not receiving services paid for.

And finally, mass/spam e-mails are much like mosquitoes, in that they can transmit viruses.

If you have to resort to mass e-mailing to get $$, then you don't have much of a product in the first place.

Business relationships are established by providing a quality product at a competitive price. Distribution chains are established by meaningful relationships, not bulk mass e-mail, "Click here to learn more" garbage.

To pass on the cost of advertising to consumer, that is the cost of e-mail storage and system resources serves to anger the consumer and does not resort in a sale.

Internet marketing groups make money by praying on peoples ignorance, claiming the benefits of mass e-mail in order that someone buys their 2 million e-mail address CD, but for those who are in the business like myself have learned, mass e-mail will result in much hate mail and your ISP shutting down your account. The small number of sales you might get from such a mass e-mail campaign, do not outweigh this disadvantage.

So grow up, go take a basic business ethics course, and produce something of value that people want, and snap out of your dreamy/illusioned world that unsolicited mass e-mail is a viable form of advertising.

I agree whole heartedly with the above statement. I do however want to point out that it is the intention not the technology that should be questioned. I am working on a mass mailing engine for the Amber Alert system where the mail I am sending can literally be the difference between life and death for someone as evidenced so clearly in recent news stories. It all comes down to respect and responsibility. Spammers are bottom feeders and only they would argue the point thus we must support, pass and enforce land based laws to chase them from cyber-space and back under the feces from which they crawl. But hiding the technology only makes them more money and hinders legitimate uses. Just my $.02

P.S.
Apologies to the feces for the association
