Re: Roundcube: relay not permitted
Hi....It could be that the remote site's ISP ip address was set on the Exchange SMTP virtual server as allowed to relay. When changing ISP's they got a new ip address.Note that if you must allow relaying, this is not the best method. I would recommend switching to authenticated relaying. pcb assembly
