Hi!
Last week all worked as expected. The hundreds of spam droped to 0; until this weekend. Looking at the headers, mail is going directly to the mail.domain.tld even though it isn't listed as mx anywhere.
Yeah, I've heard other stories of spam bots caching old MX records for months after they've been changed in the DNS.
I've seen it YEARS later personally.
Yups here also. Bye, Raymond.
