Using Gmail as your mail server
Gmail allows you to use POP3 to access your mail account. This means you can use any Gmail account to send page change notifications to subscribed wiki users.
Configuring your wiki
Just edit your wikiconfig.py :
# Mail
# Configure to enable subscribing to pages (disabled by default)
# or sending forgotten passwords.
# SMTP server, e.g. "mail.provider.com" (empty or None to disable mail)
# The default port is 25 but Gmail uses 587:
mail_smarthost = "smtp.gmail.com:587"
# The return address, e.g "My Wiki <noreply@mywiki.org>"
mail_from = "The Name you want <gmailusername@gmail.com>"
mail_login = "gmailusername gmailpassword"
