Hi, I am having a major headache here. Doesn't ISPConfig support dots in emails? Creating a new mail user like this: name: whatever email: firstname.lastname@example.org username: whatever And guess what! It doesn't work. Then deleting this user, creating an alias for an existing user on that domain.tld - an alias looks like this aswell: test.whatever. And guess what! It doesn't work aswell. Should it be this way? If not, am I missing something? How do I fix it? Cheers.
