[SOLVED] mailing list always Greylisted

I constantly get Recipient address rejected: Greylisted for 60 seconds; if I send an email to the mailing list from merlin.infradead.org and bombadil.infradead.org

and for sure 60 seconds has passed since the first try

or this could be the true problem ? Could not complete sender verify callout
yahoo,gmail and other private servers are accepting the mail from this account !

You need to register. Did you register? If not, then the greylisting is indeed misleading.

Edit: boy, old post...

they fixed it sometimes
