Main Sending from Windows Mobile

[viperiii]

Okay.... I'm really trying to get this right...

This is the same issue and error that I get when My PDA tries to send mail... However My Port 25 is open because I get mail all day long on all accounts and even my pda pops the accounts that are actively getting mail...


my main.cf is pretty basic...
However this is the questionable area...
mine:
smtpd_sasl_security_options = noanonymous, noplaintext
Others:
smtpd_sasl_security_options = noanonymous

Should I allow Plain text is this my only problem?

I only speak english so I don't know if its been solved in the German side a million times... searching I didn't find it so Here I am getting ready to be flamed!
