  • How To Block Spam Before It Enters The Server (Postfix)

    Author: Falko TimmeTags: , Comments: 12

    How To Block Spam Before It Enters The Server (Postfix) The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

  • Retrieving Emails From Remote Servers With fetchmail (Debian Etch)

    Author: Falko TimmeTags: , Comments: 9

    Retrieving Emails From Remote Servers With fetchmail (Debian Etch) Fetchmail is a program for retrieving emails from remote servers. Imagine you have five email accounts on five different servers. Of course, you don't want to connect to each of them to get your emails. This is where fetchmail comes into play. If you have a user account on a Linux server, you can make fetchmail download emails from remote servers and put them into just one mailbox (the one of your Linux user), from where you can retrieve them with your email client (e.g. Thunderbird or Outlook).
