Here I have configured sendmail server with basic setup. My Public IP also registered even I have given reverse entry in domain control. My problem is if I sent mail from normal user prompt using command 'mail firstname.lastname@example.org
' all mails are going into spam. If I sent same mail using Outlook and Evolution then some mails are going into INBOX and some users mail are going into spam. Why this happens I didn't know ? If anyone knows this please help me. If I need to do extra configuration sendmail.mc ?
Thanks in advance.
