If you use the Chilkat Email component and want to send emails using GMail's SMTP server, you need these settings:
SMTP Server: smtp.gmail.com Port: 465 Userid: your gmail username (without @gmail.com) Password: your gmail password (see below if you enabled 2-step verification) SSL: enable this option TLS: disable
However, if the gmail account has "2-step verification" enabled, you must have an application specific password to be able to send emails.
On the following window you can add an application specific password for your program.
