Mail delivery fails: "Must issue a STARTTLS command first"
Posted on 2008-02-11
I've a running Exchange (SBS) on pc-manden.net. But I'm so far been unable to recieve any mail, everything is bounceed with the message:
"PERM_FAILURE: SMTP Error (state 12): 530 5.7.0 Must issue a STARTTLS command first"
It has something to do with the security measures, but I've tried following several guides, none of them helped me.
As far as I can tell this is only part of the problem, because I get several other 'wrongs' when checking the domain with different tools. One said that there where no MX record at this domain, but that isn't true. It's there and it's defined in the DNS...
