I've followed this tutorial , and overall it's Ok i've got allmost everything working fine, exept for email. I can see the squirrelmail login page when i do www.domain.tld/webmail, i'm able to login using the accounts i create inside ispconfig. What's missing, i cannot get nor send messages to any email. I've tryed to send an email from a gmail account to one of the new emails created, and it fails sending, i cannot recieve, tryed the other way around, send an email from the new email to a gmail account it dosent get there, so at the moment i cant send nor recieve emails. How do i fix this? i'm a newbie, configuring servers. Thanks in advance.
