Email Sender Id

P: n/a
I'm sending emails from my application using the System.Net.Mail namespace
functions.

I've noticed that when e.g. Hotmail receives my mail, it blocks it and says
it can be harmful because of a missing Sender ID.
I found this text on Microsoft.com

How Sender ID Works
Sender ID seeks to verify that every e-mail message originates from the
Internet domain from which it claims to have been sent. This is accomplished
by checking the address of the server sending the mail against a registered
list of servers that the domain owner has authorized to send e-mail. This
verification is automatically performed by the Internet service provider
(ISP) or recipient's mail server before the e-mail message is delivered to
the user. The result of the Sender ID check can be used as additional input
into the filtering tasks already performed by the mail server. Once the
sender has been authenticated, the mail server may consider past behaviors,
traffic patterns, and sender reputation, as well as apply conventional
content filters when determining whether to deliver mail to the recipient.

My problem is that my email address is from my web hotel provider and
because of restrictions with my ISP (which is NOT my web hotel provider), I
can only send mails using the ISP SMTP server. That means that my mail is
e.g. me@mywebhotel.com whereas I'm sending it using the smtp.ispname.com
SMTP server.

My question is now: How can I make sure that my mail is not blocked? Is
there any way?

Cheers,
