Tips and tricks for reducing e-mail spam

It is difficult to impossible to keep the inbox for 100% spam-free.
But you can reduce the amount of spam somewhat - if you take a few tips to heart:

• Never reply to spam e-mailseven if the temptation is sometimes great
  With your reply you only confirm to the spammer that he is dealing with a current, active e-mail address.
  So don't get carried away with an angry reply to spammers either ;o)
• Never click on links in spam emails
  Sometimes spam mails contain an "unsubscribe link" or similar.
  You should not click on it, even if the attempt is great - because this way the spammers know that this e-mail address is still active and the e-mail address will not only continue to be used but will also be resold. So you end up receiving even more spam.
• Choose an "unusual" e-mail address
  Many spammers generate out of known Domains automatically e-mail addresses.
  For example, your domain is "my-xyz-domain.com" - now the software of these spammers generates common email addresses for this domain, such as "info@meine-xyz-domain.de" or "webmaster@meine-xyz-domain.de".
  In order to avoid falling into the "Spammer trap", an address such as "info-23abc@meine-xyz-domain.de" would be better.
• Block images in emails
  By calling up the images sent with the e-mail, the spammers learn that the e-mail address is active.
• Do not publish your e-mail address
  Just as you should not publish your home address everywhere, you should not publish your e-mail address (on websites, blogs, forums, etc.)
• Use anti-spam software
  Anti-spam software can help, but this software should always be up to date.
• Create an additional (second) e-mail address
  Use this additional e-mail address for forums, blogs, orders, etc.
  As soon as you receive spam via this address: Simply delete the address and create a new one ;o)
• Encoding e-mail addresses on the web
  If you publish an e-mail address on your own website (e.g. in the legal notice), it should be coded.
• Competitions
  Many competitions only exist to collect e-mail addresses. So if possible, avoid participating in such competitions with your "main e-mail address".
• Rejecting non-existent users
  In your webspace administration (our customers use "Plesk" here), specify in the e-mail settings that e-mails to non-existent users are rejected.
  So redirects or "Catch All" are rather unsuitable for combating spam.
• Use greylisting spam protection
  Since our customers use the web space management "Plesk" and also use "Greylisting" is activated, our customers can activate "Greylisting spam protection" in the e-mail settings.
