Hi,
I am new to Linux and I have recently installed Postfix on my centOS system. When sending e-mails to gmail or hotmail my messages automatically get redirected to junk mail or dont get delivered at all. Does anyone know why this is happening? I am also having issue with receiving e-mails from gmail/hotmail accounts.
I have read on one website that this issue could be cause by my IP address being blacklisted OR could be caused by a dynamic IP. Is this true?...
