Cant send email new install ispconfig 3 on ubuntu 11.10

[kvess]

Thank you for all the help you are providing but, here is the thing when I try to install

Package ia32-libs-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
ia32-libs lib32z1-dev lib32bz2-dev

When I try to install the candidate it has a lot of unmet dependencies.


Thanks
