Maybe, Stephen, but it is not a new installation, but and old one. It just stopped working this morning (that is, about 10 hours ago) without me doing anything. I just woke up and when try to send a mail, I coudn't. I didn't get any error message, quite opposite, DQW Mail said the mail were send. Last night, it worked fine. Fortunately, DW Mail knows how to use SMTP so I have switched to it i order to let people use DW Mail as I have 100+ people that are relying on it. This is good since 99 percent of the people are on mail3, I have only one domain that is on mail4. The problem is that they were used to read their other mail with it too and this is not possible anymore since in order to make it work I have "glued" it to mail3.
