thank you so much. Now i am able to send mails, but the problem i noticed is that the mail is going to the BULK folder of the person whose email address i am writing in TO field, and also when i specified CC field and a email address then mail goes to the INBOX folder. What is the reason behind this.Plz.
So do you have any solution for this.

Re: Email Sending Problem in ASP.NET

dude

ofcourse the mail will reach the bulk mail because ur server isnt known to the server u r sending the mail.

u can do the thing to make the mail goes directly to the inbox but i dont know it and i heard it ****ing hard. u have to play with some protocols and other shits.
my advice to u is to be happy with wht u got.
