Hi I'm setting up a Joomla Application for delivering emails using gmail smtp server. I made use of it on my small localhost and located to operate properly. Nevertheless its not focusing on my remote host server. I'm utilizing the same configurations for this. Can anybody reply me the issue. Its states that email couldn't be sent

Have you sent bulk mails, news letter and etc ?

if the reply is "yes", you can examine your gmail account, because gmail smtp server includes a wise bulk spamer recognition engine. so that they may deactivated your smtp account due to delivering about a lot more than even 50 mails in last ten mins.

so my suggestion would be to forget gmail as the smtp server and begin your personal smtp server or purchase a compensated smtp account to get this done.
