Hi all I know that qmail is unsupported. However, i would like to continiue use it. So, is possible to install ISPConfig without postfix/sendmail? If not, is possible to install postfix , then ispconfig ,then remove & finally install qmail which will be configured manually? Or ispconfig hould have all programs (bind9/iptables/etc...) under his control?? Thanks in advance
No. This might work, but you will not be able to install any ISPConfig updates in future and I really do not recommend this. Postfix is a fine and fast mailserver, if you want to use ISPConfig then you should switch to postfix.
