I would like to send mails using a proxy server.I'm using System.Net.Mail to send mails.
Would adding the following settings do?
Your response is greatly appreciated.

Mifla, i do not understand your question, so i need to ask you more information.
184.108.40.206 pings, so it's a live computer; ip2location shows it's in Egypt; ip2location and nslookup both show tedata.net.
http://www.tedata.net/eg/en/About-Us/About-Corporate shows that TE Data is Telecom Egypt,.
is TEDATA your internet service provider?
is host-220.127.116.11.tedata.net (18.104.22.168) an e-mail server?
Note: AFAIK, you can not in c# proxy any e-mail server; i could be wrong.
"Gets and sets the URI that identifies the ==>
Web <== proxy server to use."
System.Net.Mail requires that you specify a SMTP host.
FWIW, i doubt you can proxy a SMTP host ... so, unless host-22.214.171.124.tedata.net is your e-mail server, or an e-mail server that TE Data has allowed you to use, you can not use it.
i'm guessing that, assuming you have an e-mail account with TE Data, you simply need to speciify something like smtp.tedata.net as your e-mail host, plus your e-mail account id, plus your e-mail account password.

Many thanks for your response. I am developing an application that will send out millions of mails as part of an email campaign. So if I send from the same IP always, I might get listed as SPAM. Ideally I plan to use proxies listed in http://www.proxyfire.net on
a random basis.
Is this possible? If not what can I do to overcome this?

Mifla, if you do not have permission from the recipients to send these e-mails, there is a good chance that what your are sending will get classified as spam, a.k.a. UCE ... unsolicited commercial e-mail.
Bad things can and likely will happen to you.
a customer of mine has pre-qualifed business clients ... his clients have consented in advance to receive annoucements from my customer about product upgrades ... one of his pre-qualifed business clients forget their agreement and complained to my customer's
isp ... that isp blocked my customer's internet access without even contacting my customer first.
Mifla, learn how e-mail works ... quick, very simplified summary ...
your computer (client) ==> your smtp server ==> MTA ==> MTA ==> recipient's POP server ===> recipient
Chances are good that your millions of e-mails will be detected and blocked by a well managed MTA.
see, for example:
Also, the recipients' computers will likely block your e-mails.
Mifla, perhaps you can share with us why your millions of e-mails are not spam?
P.S.: if a site like proxyfire.net is giving you ip addresses of open, unprotected SMTP servers, it is highly likely that those open servers are already blocked ( i could be wrong ).
Mifla, to use any SMTP server, you need to know what that server requires in order for you to use it.
For example, i can not use my isp's server unless i provide both an account and a valid password for that account.
