Hi Nii, Probably this has been caused by the server being incorrectly configured to send mail. There are many spam filters out there, but things to check: * reverse DNS - I had this problem a while back, some clients weren't receiving mail. It is important the server gives the correct DNS name on the SMTP helo as the receiving server can look up from the reverse DNS. * check www.dnsreport.com . This can point out other problems with mail delivery. * check the obvious - logs etc. It is possible that the headers are dodgy in some way or something else is unusual. Good luck and happy new year, Alex
