Verify Email Delivery?

Question:
Is it possible to check if an email is delivered properly?

Answer:
The Chilkat MailMan is an SMTP client. It connects to an SMTP server to initiate the delivery of email. Typically you would connect to your company’s or ISP’s SMTP server. If the email is to be sent elsewhere, the SMTP server relays the email to the remote SMTP server (or to some other intermediate mail server). The SMTP client can only report back whether the initial “handoff” is successful. There are cases where the initial “handoff” fails, and these would result in a failed status return by the mail-sending method call.

Email Bounce Processing Examples
* When sending email, you may set the email address’s BounceAddress property to specify a mailbox where bounces (i.e. DSN’s) are to be sent. You may write a separate application to read that mailbox using Chilkat Email (or Chilkat IMAP) in conjunction with the Chilkat Bounce component to categorize emails as bounces or not bounces, get the type of bounce, and the original sender (if possible).
