Hey there, Im pretty new to linux and and custom panels so maybe the questions could be stupid. I installed ipsconfig using this guide : http://www.howtoforge.com/perfect-server-debian-wheezy-apache2-bind-dovecot-ispconfig-3-p4. And I have some problems: 1)When i connect to my server it says that the ssl certificate is invalid 2) Same for the email and thurderbird states they aren't protected. Overall what should i do for this ssl certificate? and here we go with the stupid question: it is free or im making a huge mistake? 3) Thurderbird accepts the emails i created with ipsconfig, i can write and send them but it doesn't find new mails. Instead i can see the new mails only on the squirrel client. How can i fix this? I tried tosearch on the forum but couldnt fix these problems (working on the vps by hours...hours.... xd, the rest of ipsconfit seems fixed now ). thz in advance.
