[Typo3] spamProtectEmailAddresses=-3 and underscores in email-addresses

[Christian Stuedemann]

Dear list,

please note: If you use spamProtectEmailAddresses=-3 the underscore
("_") in email addresses will be encrypted to a backslash ("\"). This
backslash might not be decrypted correctly. It might just be ignored. In
this case the underscore is missing in the decrypted email address.
Solution: Use any other offset (-4..+4) except -3. This will solve the
underscore problem.
I don't know if this bug is a general one or if it is just occuring on
my page. Please check and confirm/disagree.

Best regards,
stuedemann
