Hello again, I apologize that in my previous message I didn't provide additional informations. I was hoping to be a trivial problem(and it was), so it doesn't need too much to be solved.
I've solved the problem after sending my first post. It was in main.cf, the following statement: smtpd_sasl_exceptions_networks = $mynetworks Commenting it out solved all problems: - first: the MsOulook2007 must to have "Log on to incoming mail server before sending mail" option checked. - second: mobile android device access(through local net) and smtp auth offer; Hoping this will will be useful sometime, I thank everyone who read my message. -- Best regards, Gmail-teopro mailto:teo...@gmail.com
