Sending Emails in Sharepoint - sharepoint

Question

I need to know what is the best practice for sending emails from my sharepoint webparts and/or customized features.
Should I just use the normal .Net classes to send email ? or is their a better way to do it through integration with an outlook server ?

Answer 1

Easy way is to use the built in Utilities, this will then use the mail server setttings setup in central admin
using Microsoft.SharePoint.Utilities;
SPUtility.SendEmail(SPContext.Current.Web, false, false,
"toaddress#mail.com", "subject",
"body");

Answer 2

Universal way to send email in any context(where SPWeb not available) is read OutboundMailService settings which is used in SPUtility. Then create SmtpClient manually:
var adminApp = SPAdministrationWebApplication.Local;
var instance = adminApp.OutboundMailServiceInstance;
var server = instance.Server.Address;
var defaultFrom = adminApp.OutboundMailSenderAddress;
var client = new SmtpClient();
client.Host = server;
message.From = new MailAddress(defaultFrom );

You also can use this code for dynamic mail id. this code gets the mail according to the user. I have used CAML query to get the data for the email content from the lists.
SPUser AssigUser = oWeb.EnsureUser(Assigned_Username);
SPQuery mquery = new SPQuery();
mquery.Query = #"<Where><Eq><FieldRef Name='Email_x0020_Type' />
<Value Type='Text'>Review - Ready for Review</Value>
</Eq></Where>";
string Emailsub = "";
string Emailbody = "";
SPList mList = oWeb.Lists["Email Content"];
SPListItemCollection itemcollection = mList.GetItems(mquery);
foreach (SPListItem item in itemcollection)
{
Emailsub = item["Email Subject"].ToString();
Emailbody = item["Email Content"].ToString();
SPUtility.SendEmail(oWeb, false, false, AssigUser.Email, Emailsub,
Emailbody + "</br>" + oWeb.Url);
break;
}

using overload with StringDictionary arguments (source)
StringDictionary headers = new StringDictionary();
headers.Add("to", currCtxt.Web.CurrentUser.Email);
headers.Add("cc", "xyz#abc.com");
headers.Add("bcc", "");
headers.Add("from", "email#add.com");
headers.Add("subject", "Email Subject");
headers.Add("content-type", "text/html");
string bodyText = "Hello how are you?";
SPUtility.SendEmail(currCtxt.Web, headers, bodyText.ToString());
