Strange mail behaviour - various rejection

[coolemail]

thank you both for your education and help on that. I do not have a morercpthosts. But some of what you say, and the link, suggests that some people may have a huge file. Do you? I have never had cause to create domains in this and I'm wondering whether there is something common which I have missed that others do fairly regularly.

We only use it on Project Gamera mail servers, not on Plesk machines.
