I've only just set up Zoho for my system.

So I went to send an email to my 600 members of my forum to inform them of the situation that we've now got a proper email provider.

As is typical with any forum, quite a few members have used temporary inboxes or were just spammers, but in both cases, their email addresses would bounce.

My sending has now been blocked, but I really need it unblocked. Can this be done so sending can resume?

Thanks.
