sending email using SMTP in asp.net

using SMTP to send email.

is there any settings need to be configured apart from Host name and
Port, while sending emails using SMTPClient in .Net?
when i try to send mail to ids which has only one dot in the domain
name (eg : te**@abc.com) there are no issues.
but when the mail ids are like (te**@abc.co.in or te**@abc.rr.com) the
mail is not getting received by those ids.
also, there are no exceptions occured when i debugged it.

this is the code i have used:

MailMessage msg = new MailMessage(fro mId, ToIds);
SmtpClient client = new SmtpClient();
client.Host = hostName;
client.Port = port;
client.Send(msg );

thanks,
shan

SMTP clients have rules who can forward through them. In general, your own
domain works, but anything other than that domain is refused. This is a
setting on the mail server, not in the ASP.NET application.

An email address is an email address and it really shouldn't matter at all.
Since 'ToIds' is a variable, what format is the variable in (assuming
multiple email addresses)?

It only matters to the email server, which by default should block addresses
outside of the domain.

Years ago, this was not true, and people would find a UNIX/Linux server with
SendMail in default install. You could then send email through that server
and it was very hard to trace it back to the originator. Today, the normal
default is "only from my domain".

I want my users to send emails from a Windows app that I am developing in Visual Basic.NET 2003. I found a good example of sending email to a SMTP server using the SmtpMail class. However, using this, it seems, that the user must install IIS on their computer. Isn't there a class that will detect whatever mail server is available on a computer and use that? How do I create this functionality without having the user add any other...

I've built a small app that sends mail through our ISP's SMTP server but when I try to send through my local exchange server I get CDO error. Does webmail use SMTP or does it strictly rely on CDOmail. I don't want to use the Outlook reference because outlook prompts each time program access it and I have found a way to disable that. Can I use webmail with exchange? Thanks

Hi, I'm using the MailMessage & smtpMail classes in System.Web.Mail to send mail, however it's not sending any emails. I'm using it on a Windows 2003 server.
