I think everything was working fine but after update main.cf file i'm
seeing the following warning for emails incoming outside the box,
postfix/smtpd[15455]: warning: restriction
`reject_authenticated_sender_login_mismatch' ignored: no SASL support

The previous warning is show when i send an email from GMail to a domain
whose email is managed by me.

Basically what i did is:
* Remove permit_mynetworks where i think it shouldn't be.
* Disable smtp auth globally and enable it at submission 587 and smtps 465.
* Remove the deprecated smtp_use_tls/smtpd_use_tls statements.

Here i paste my current main.cf and master.cf files.

Any help would be extremely appreciated. Thanks in advanced!

but it is using aliases table specified in main.cf also uses an email
rewriter table specified in main.cf If possible would like to create an
exception table. The case is i would like aliases to be only used for
recieving and forwarding to real email boxes. I do not want to let users
login through aliases. Also i would like some users like root to rewrite
its email.

emails first get smtp it gets rejected if login missmatch sender address,
then don't know why it is passed to amavis content filter when it really
should get rejected and after amavis injects the email again into smtp it
gets delivered. It's pretty weird, but i'm not able to find my mistake.
