Q: How many emails can I send via SMTP? Is there a limit?
A: Yes, your outbound email messages are limited to 500 per day, and each message can be sent to no more than 100 contacts at once.
In an effort to help protect all of our customers from spam, Yahoo! has become more aggressive in its requirements around SMTP limits. In addition to placing limits around the number of emails you can send from your desktop email software each day, we reject connections that don't conform to Internet best practices.

http://help.yahoo.com/l/us/yahoo/sma...op/pop-36.html
If you are hitting up against these limits, then I suspect you are trying to build a SPAM system and I doubt anyone here is going to help with that.

i am not going to build a spam but i am responsible for advertising in a company and i send messages to thier customers a bout thier products so i need to send the add to all the customers in one day not to send 500 add per day
i hope i can find help

yahoo mail or gmail via my local smtp

This doesn't sound like a corporate job sending mail to their customers. Maybe I'm wrong, but any company with a mailing list of 500 customers a day can just set up their own mail server and would not be going through Yahoo mail or G-mail.

So, if this is a legitimate work need that would be my recommended solution: To use the company's own mail server.

[remohy1]

dear sir its not a great corporate but at all i think u are going to understand my question "local smtp" this is what i am asking for

[Plater]

@remohy1
Did you turn on the local SMTP server?
It's a service called "Simple Mail Transfer Protocol (SMTP)" and is part of the iis suite I believe

[remohy1]

i have configuered it but i dont know how to use it
what is the smtp address that i can use as i used "localhost" but it dont succeded

[Plater]

You would connect to it through localhost, but there will be no "myname@localhost" emails

This is a .NET1.1 project is it (visualstudio2003)? I've never seen the Fields[] property used like that, so I cannot speak to how that works. I was not aware you could get the old version of the smtp to authenticate either.

[remohy1]

its working in vs 2005 and vs 2008

[Plater]

Well System.Web.Mail is depricted after .NET1.1, you should be using System.Net.Mail instead.

[remohy1]

this is not the problem
my question is that i am responsible for sending adds and that i succesfully send it via yahoo or gmail smtp but i asked can i use my local smtp to avoid limitation of 500 mail per day??

[Plater]

Well if you are using depricated classes, that are not working, because they were not designed to do what you want....What do you expect a magic solution?
If your local SMTP server is on, I am pretty sure you specify no host or port number and uses them by default. At least thats the way the correct versions of smtp classes are suppossed to work.

[remohy1]

if i searched the web or someone here helped me to configure local smtp on the right way does it will work on gmail or yahoo mail?

[tlhintoq]

@remohy1
You have to pick one or the other... You either send through Yahoo as your SMTP host, or your own PC as the SMTP host, or Gmail as the SMTP host, or NetIdenty, or NetFirms...

Wanting to send through Yahoo yet send through your own SMTP doesn't make sense. Its like saying I have to drive my Dodge Ram Pickup, but I still want to do it through my VW bug.

[remohy1]

so you mean that i cant send from yahoo mail via my local smtp
this makes a problem for me that i wanna recieve the orders on my yahoo mail so i think the result that i have to send 500 mail every day
am i right?

[Plater]

If you want the reply emails to go to a yahoo account, you either have to rely on some trickery (setting the reply-to address to your yahoo account, which some email programs detect as a spam warning) and using the local smtp server
OR
You have to use the yahoo smtp server, which requires authentication, which means you have to switch to using system.net.mail, and I am not sure yahoo even allows smtp access. Gmail WILL, but you have to "opt in" through the settings section of the webpage

[remohy1]

@Plater
i can use gmail mail but what do you mean with
"with requires authentication" at all this is the only way i found on the internet wich allow sending mails via vs005 do you have any other succesful ways that achieve the goal you ment "Gmail allows smtp access" and what does it means?

[Plater]

It should have said "which requires authentication", meaning you have to "log in" to the smtp server with valid credentials.
GMAIL allows you to use their smtp server if you enable it in the settings page, but they use a special type of smtp server and it also requires encryption

[remohy1]

do you have a link that explain what you said :
"GMAIL allows you to use their smtp server if you enable it in the settings page, but they use a special type of smtp server and it also requires encryption
"

[Plater]

Log into your gmail account, and go to settings. Flip through there until you find the section for allowing SMTP access.
You could also just google it, they have plenty of directions about it.
And plenty of people on here have asked questions about using gmail through .NET.

thanks alot for helping
