iis smtp nntp
group:SMTP Server won't send BCC from a webmail app.
iis smtp nntp:
a simple mail app created in vb.net. I am trying to make an app to send out our company newsletter to several thousand people. In my app, I am just sending them to three people (just the site admins). The only email that arrives is the one in the to field, but none in the BCC field. Each email is separated by a semi-colon. The code side is pretty simple, and it works on other servers. Does this sound like an SMTP server issue? How might I test out the server to see if the same email could be sent another way?

What should I look for (sorry, I'm new to smtp admin. We just switched to a new server where I am responsible for handling this.)

Well, speaking for myself, I am sending a copy to each of my email addresses. I am using Outlook express to retrieve my emails, and I don't know of any spam filter in use. Since I am using BCC, wouldn't the email client view it as a singular email? [quoted text, click to view] > PeterD, the Darkstar Network > To email, fix my address! > ExpertZone!

Follow up. I tried it on another server, one with considerably less load, and set up the basic smtp, and it's working. FWIW Thanks, everyone.

What should I look for (sorry, I'm new to >smtp admin. We just switched to a new server where I am responsible for >handling this.) If the messages got sent, it's not your end that's the problem. Perhaps spam software on their end. Try composing three separate emails in your app.

Then Outlook (or agent, or Thunderbird, etc.) takes that email, and creates four emails. The email to Bob contains only Bob's name/email in teh addresses. The email to John contains only John's name/email in the addresses. The email to Mary contains only Mary's name/email in the addresses. and The email to Paul contains only Pauls name/email in the addresses. With BCC, the CC fields are left blank. ---Regular CC: ---- You send a (regular) CC to Bob, John, Mary and Paul. Then Outlook (or agent, or Thunderbird, etc.) takes that email, and creates four emails. The email to Bob contains Bob's name/email in the addresses, and John, Mary and Paul in the CC field. . The email to John contains John's name/email in the addresses, and Bob, Mary and Paul in the CC field. . Same setup for the others. Again four emails, but with regular CC messages the CC field(s) are filled in. Regardless of BCC or CC, the server sees four emails (one for each of the four). The difference is taht BCC won't fill in the CC field (so no reply all!) and since the CC field is blank the receiving end doesn't know about the BCC part. That is a simplifiation soemwhat, as you can mix these two models. PeterD, the Darkstar Network To email, fix my address!
