Hello, I ran into a strange problem yesterday. I am totally unable to get mail generated via the php-mail command to be delivered on any local e-mail address on the same server. The mail addresses work perfectly when mail from the outside is sent to them, and the php mail function also works smooth when sending mail "to the outside". So an e-mail form on www.domain1.com can't send mail to firstname.lastname@example.org or email@example.com (which resides on the same server) but it can send to firstname.lastname@example.org which runs at another server. email@example.com and firstname.lastname@example.org can receive mail send via other ways (hotmail,gmail, outlook). Any suggestions would be appreciated.
