I've just tried sending a message to sales <at> eukhost.com and it's bounced with the following message:

(Tha @ symbols above have been manually change to <at> as an anti-spam attempt.)
I sent it a second time having removed the company logo in case that was the problem. Is there a problem with your email system. I haven't had that reply from any other mails I've sent today.
