OK. I’ve messed up somewhere and I don’t know where but all external emails are being rejected.
Does anyone have a working config file that supports SASL for both POP and SMTP please as right now, I can’t receive any emails from external sources on my internal site.
Alternatively, if someone could give me a few pointers of which bit I should look at in the main.cf or master.cf (or even both) then I will try and “rebuild” my config files accordingly. I am using the default POSTFIX/Dovecot install.
I don’t really want to have to start my server from scratch again but I’ve read you can’t reset POSTFIX back to defaults unless you have a backup, which I don’t (silly me, but I haven’t finished sorting everything yet).
As always, any help is appreciated.
