TYPO3: Encrypting your emailadresses by default
To reduce spam people have found numerous ways to place their email address on a website. TYPO3 can encrypt your emailadresses by default though. Just put the following lines in your Typoscript Setup:
config.spamProtectEmailAddresses = 2
config.spamProtectEmailAddresses_atSubst = (at)
Now all @ will be replaced by (at) and the link will be encrypted.
