I am currently using Axigen but have just downloaded and installed Zimbra and it's looking good so far.

One feature that Axigen has though is the ability to set the ooo autoresponder to respond only once to any email address. Although this may seem a minor thing, when one of my users forgot to set this, she bounced thousands of emails back and forth with someone who hadn't got this option.

Is there a way of setting this in Zimbra?

Many thanks
