I will definitely send you the details but at the moment it seems a bit pointless as we cannot reply to any email or even send an email.
I have just googled the phrase I'm getting - there was an error. Validation failed for *insert our email address* - and my head is swimming. I don't know what kind of system Horde email is, but it seems a lot of buisness are using it, and lots of techno wizards as well, judging by the reponses and questions I am reading.
I have tried a few suggestions that I've read, but when people say you need to change %*($@h42718%^, they may as well be speaking Japanese. I don't think there is anything I can do with this. 
But until something works out, I can at least read emails and if I have to, I can respond with my own email address for now. The most important thing is that people can contact us if they need to. 
JF, I checked out the problem after Ea alerted me to what was going on. Looks like there was an issue with the "Full Name" field being set to Arwen-Undomiel.com - probably something about the .com in there. I changed it to "A-U Staff" and the error message disappeared. You're welcome to change the field (Options > Global Options > Personal Information > Your full name) and experiment to see what does or does not produce an error message. Hope that helps!
... so it saved me having to pass it on to an expert.
