Thank you for the very quick reply!

First of i need to tell you that i broke also the receiving part. I don't know exactly how but back tracing my steps, i did something like described here:

Anyway, to your request:

I am not sure how back you want me to go so i will stop here.

OK so i am getting closer now. I found that adding relayhost = smtp.ziggo.nl on main.cf allows the emails to reach my ISP relay host. Problem now is the authentication.

I realised that the reason i am getting the error fatal: SASL library initialisation has something to do with the sasl and postfix.

I have no idea what it is or how to fix it, but i will continue looking. In the meantime, if anyone has anything to add... please do so! It will save me few hours

Did that, this is the log:

i tried activating through webmin and i got the same result. definitely the error is something with smtp sasl.

I have seen this site already but i don't know / understand what the heck i need to do to fix it

I understand that the problem is exactly the "fatal: SASL library initialization" but i have no clue how to fix it

One question though that i have which may (or may not) help me. How does the whole thing works? postfix receives the emails from the client and then sends directly or is it using something else in between for the MTA?

I am trying to look at it from all angles but again, i don't really know what i am doing :S

That solved the problem!
