Gmail: IMAP, POP3, and SMTP settings

Gmail supports access via IMAP, POP3 and SMTP protocols. Below you can find the configuration settings for all protocols.

All Gmail servers (IMAP, POP3 and SMTP) use implicit SSL – use ConnectSSL method.

IMAP

Server: imap.gmail.com
SSL: true, implicit
Port: 993 (default)
User: pat@gmail.com or pat@your-domain.com

POP3

Server: pop.gmail.com
SSL: true, implicit
Port: 995 (default)
User: pat@gmail.com or pat@your-domain.com

SMTP

Server: smtp.gmail.com
SSL: true, implicit
Port: 465 (default)
User: pat@gmail.com or pat@your-domain.com

Following are the code samples for Mail.dll .NET IMAP, POP3 and SMTP component.

Remember that you must enable IMAP in Gmail or enable POP3 in Gmail first.

// C#

using (Imap client = new Imap())
{
    client.ConnectSSL("imap.gmail.com");
    client.UseBestLogin("pat@gmail.com", "password");
    ...
}

using (Pop3 client = new Pop3())
{
    client.ConnectSSL("pop.gmail.com");
    client.UseBestLogin("pat@gmail.com", "password");
    ...
}

using (Smtp client = new Smtp ())
{
    client.ConnectSSL("smtp.gmail.com");
    client.UseBestLogin("pat@gmail.com", "password");
    ...
}

' VB.NET

Using client As New Imap()
	client.ConnectSSL("imap.gmail.com")
	client.UseBestLogin("pat@gmail.com", "password")
	...
End Using

Using client As New Pop3()
	client.ConnectSSL("pop.gmail.com")		
	client.UseBestLogin("pat@gmail.com", "password")
	...
End Using

Using client As New Smtp()
	client.ConnectSSL("smtp.gmail.com")
	client.UseBestLogin("pat@gmail.com", "password")
	...
End Using
