Google apps email
I have had problems with mail servers in the past. I elected to set up email with Google Apps. I used the guide in your resource section and set up the MX records on the linode DNS system.
I am receiving email to my new business gmail name:
What do I need to set up on my linode?
Mail servers are frustrating.
inet_interfaces = loopback-only myorigin = $mydomain mydestination =
If you want your Linode to funnel all outgoing mail through Google Apps, that's slightly different.
Thank you for your reply.
I would only like to send mail from my domain, and only mail that originates at my domain, specifically from a discussion forum. I had mail set up without problems for years. However, I my server was hacked last year and was used to send out spam by the ton until I took it off line. I don't want that to ever happen again.
I will give your suggestion a try and see if I am able to secure the source of the outgoing email.
Note that any mail which originates locally will be sent, such as from web forms. So it is important to make sure those can't be used to spam people. There are a variety of ways to prevent that, such as restricting the destination e-mail address, adding a CAPTCHA, and rate-limiting form submission. Many well-written web applications already build in some protection; if your forum is one of the popular ones it probably is OK.
Of course, if someone gets shell access to the machine all bets are off. The basic security guidelines in the Linode docs are pretty good.
