What is smtp host? and how do i obtain it?

we program a niche site.and i’d like to send out a message on the user..at this point in asp.net from the config track..i place this:

i have no clue how this network web host acts plus what it will..i prefer to change it into the server which holds our yahoo account.i understand that smtp is definitely some contact server which sends postings out..but how do i put get hold of it can it mimic, is this an int, can it be a chain!

It is a string.”server.sector.toplevel_domain.” It’s going to usually be such as “smtp.mailHost.com” and also “mail.mailHost.com.”

No a smtp server seriously isn’t a stringed..its a server.

You utilize a link with reach this server, and it typically listens with port 25.
should you be testing with localhost, you have to probably yahoo and google how to begin localhost smtp or maybe update your current web.config to use a mail server

i have to take any tip with these types of network hoster.
