I've searched around and am semi confused. ispc 3.0.5.1, Lenny 64, courier, mydns. I upgraded roundcube to 0.9 which I now see requires php 5.3 so now I have broken webmail. (if you know how to downgrade that will help also). If I can't downgrade then I need to add php 5.3 to my install and only use on webmail domain. I know I can add the php in ispc and provide the path to the binary (?) as a Multiple instance. My problem is that if I add php 5.3 via dotdeb (http://archives.dotdeb.org/ and use dpkg -i to install the packages by hand) then won't that UPDATE my current php? I only want to add this as an additonal install. Any guidance will be grateful...either in downgrading roundcube or adding php5.3
