Our previous developer wrote a basic aspx contact form for one of our hotel clients before leaving, all has been fine with it so far but when testing this week I noticed that although the email sent by the script was received without any issues at the hotel end - their reply to the email address i supplied on the form was marked as spam via my macs mail filter.
I should point out that the email address i used to test the form was a yahoo address which is added to my imacs mail account, when checking yahoo itself it wasn't in the spam folder and was displayed in the inbox as suspected. - it was only highlighted as spam (yellow color)on the imac. So hopefully I'm worrying about very little!
I'm hoping that the forms done its job by getting the mail to them so either just a fussy iMac which has a problem with their reply address or something else not related to the contact form itself.. If this is the case is there any advice i can offer them of anything they can add to the reply to stop it being spammed?
To clarify - the contact form sends a email to the hotel with the customers question and comments - this is received without issue. The issue appears to be when the hotel reply to the enquiry via the inhouse mail - their reply was spammed for me (mac only). The mx records for the email point to the previous domain and the site is hosted with us - the previous designer has control panel access for the DNs settings.
Update: having sent 5furtger tests from several different accounts - none were spammed. It appears to be an issue with the content on the initial email, as if I copy this into a completely separate blank email and send it to the same mac account it also shows up as spam. Is it still worth setting up the SPF thing do you think?
