Hi,<br />
<br />
After installing a sonic firewall last week all our email addresses are displaying as from @mail.domain.co.uk instead of @domain.co.uk?<br />
<br />
We are running exchange 2003 on sbs2003<br />
<br />
The sonic wall could be a coincidence <br />
<br />
Any help greatly appreciated
