I am using smtp_tls to send mails via GMAIL.
The problem is, I am trying to send multiple mails so i have to authenticate multiple times which consumes a hell lotta time, can anyone suggest a way.
First up - Gmail limits to around 500 messages/day.
I got something going using this script: Index of /blog, modified a bit for gmail's sake!
Oooh, thank you for the link
