One of my ispconfig installations has shown an odd behavior the last couple of days. It is ispconfig 3 and does NOT use a catchall. My mail server has been having high cpu loads. a little investigating found it to be accepting emails for email@example.com. the server has 2 domains tld.com and the mail alias of tld2.com that points to tld.com these 2 domains no matter what the user address is IE ERSGSEGER@tld.com or AERFWER@tld2.com, postfix is accepting email and creating a user mail folder under /etc/vmail/tld.com . for some reason the server has stopped bouncing invalid recipients and is now accepting them. Im at a loss on this one any help is appreciated.
