Strange Problem with Horde

For some unknown reason, and this may be a bit of a newbie question, I cannot send email from Horde/WebMail to any email address with a non-local domain. I get the following error:

There was an error sending your message: unable to add recipient [[email protected]]: Invalid response code received from server.

I added the localhost(127.0.0.1/32) address to the whitelist as specified in the FAQs and it didn't help. At this point I don't know where to look. I checked MailEnable and everything seems OK.
