Using gmail SMTP
To use gmail SMTP to send email from OJS system. You can use the following setting in config.inc.php
; Use SMTP for sending mail instead of mail() smtp = On ; SMTP server settings smtp_server = "ssl://smtp.gmail.com" smtp_port = 465 ; Enable SMTP authentication smtp_auth = PLAIN smtp_username = "email@example.com" smtp_password = "password"
Note that using gmail to deliver email will result in all emails being addressed "from" your gmail account, rather than the OJS user who initiated the email. You may wish to consider patching http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=8085 to allow existing installs to include a configurable prefix in email templates explaining that the message is being sent on behalf of your journal, press, or conference.
Note that you may have to additionally configure application-specific passwords in gmail; see https://support.google.com/accounts/answer/185833?hl=en for details.
