Summary:
This will now support a port config in the IMAPStore of the config. This is
still optional and will fall back to 993 if you don't have it.
It will also ignore tls verification if we have a CertificateFile config
option. This will take a bit of refactoring to implement our own tls context
so, for now we will disable it. As we have put in the comment, if the user
really wants this then they can configure this in there root store.
Test Plan:
N / A this tool is not tested yet
