Sputility. sendemail alternative solution

Some time ago it was mentioned that the sputility. sendemail method has some defects. The biggest defect is that the mail content is limited to 2048 characters. You need to set a password to use system. net. Mail to send emails. It is inconvenient to set a password in webpart. Today, we finally found a good method, as shown below:

Code
Private   Void Sendemail ( String Psubject, String Pfrom, String PTO, String Pbody)
{
System. net. Mail. mailmessage message =   New System. net. Mail. mailmessage ();

Message. isbodyhtml =   True ;
Message. Body = Pbody;
Message. From =   New System. net. Mail. mailaddress (pfrom );
Message. to. Add (PTO );
Message. Subject = Psubject;

Spoutboundmailserviceinstance smtpserver=Spcontext. Current. Site. webapplication. outboundmailserviceinstance;
System. net. Mail. smtpclient SMTP= NewSystem. net. Mail. smtpclient (smtpserver. server. Address );

SMTP. Send (Message );
}

Use the configuration information of outgoing email settings and the system. net. Mail. smtpclient class to send emails. You can use it without setting a password, and get rid of sputility. sendemail.
