There is nothing difficult in general. You only need to retrieve MX (Mail Exchange) records from a DNS server for the domain and then connect to the mail server using an SMTP component or using your own SMTP implementation. Some example: 1. You have mail to [email]john (AT) smith (DOT) com[/email] 2. Ask DNS for MX servers for smith.com 3. Connect to a mail server (like mail.smith.com) and send the message via the SMTP protocol.

Could somebody give me some simple demo to do that with Indy? Very likely it's impossible. A lot of ISP's are blocking port 25 so the only way to send e-mail is through their servers. It's an anti-virus precaution. Back to top marshmathers Guest Posted: Sun Nov 28, 2004 4:06 pm    Post subject: Re: How can I send email without ISP SMTP Server? Hi, It is possible. Use some DNSResolving component (comes with Indy) with MXQuerry. It will give u a list all the mail servers. Add it into some listbox. Take each mailserver and using some SMTP Component send mail. That's all! Quote: Hi all How can I send email without ISP SMTP Server? Could somebody give me some simple demo to do that with Indy?
