raju melveetilpurayil 15-Jul-10 10:10am

raju melveetilpurayil 15-Jul-10 10:20am

and also Enable IMAP in gmail settings [Forwarding and POP/IMAP]

sathish.kasin 16-Jul-10 0:58am

after that i enable ssl port and also change the port number , how to enable Enable IMAP in gmail settings [Forwarding and POP/IMAP]???????

raju melveetilpurayil 16-Jul-10 1:06am

goto gmail then click on setting then select Forwarding and POP/IMAP after that Enable IMAP.

sathish.kasin 16-Jul-10 1:06am

After that i add these things in code
smtp.EnableSsl = true;
smtp.Timeout = 20;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

raju melveetilpurayil 16-Jul-10 1:08am
