Postfix & Dovecot SMTP AUTH

[Rudeboy]

Could someone help me understand authentication in Postfix and Dovecot?

i've followed (and tried) a lot of the guides to add SASL authentication to my mailserver, but I can still send mails without having to authenticate, which is not what I was expecting. I'm really looking to have to authenticate to send and receive which is what I don't be able to seem to get working. Is this a problem with Dovecots version of SASL? I'm just about to give Cyrus-SASL a go and see if it makes any difference, but figured someone on here is bound to have looked at this before.

Thanks,
Nick.

Does no one use authentication then?

Is that because you have your networks listed under mynetworks and smtpd_recipient_restrictions = permit_mynetworks is set? If so you will be able to send un-authenticated. Try removing permit_mynetworks and have permit_sasl_authenticated as the first entry, before any rejections.

Thanks, I'll give it a go.
