  - by artfulrobot

  I have smtp auth set up on my exim4 Dqueeze server so that only auth'ed clients can use it as a mail relay. I believe this is working, e.g. thunderbird (w/out password) reports that I am "not yet authorised to send mail for X from Y". I also have greylistd installed, which I also see to be working. But I've noticed that when an unauthorised…

  - by Michael

In your experience does greylisting…

  I'm running a small VPS server that works as web and mail server. It has only 256MB of RAM, and it's sucking 100MB of swap constantly.
