[gentoo-user] portage: sendmail blocked by ssmtp...

[Jarry]

Hi,

I wanted to emerge "sendmail" (for a few reasons I don't want to
use other MTA), and I see, that it is blocked by "ssmtp". Because
I did not installed it, it must have been emerged as a dependency
of some other package.

Q1: Is it possible to find, which package depends on ssmtp and
     caused ssmtp to be emerged?

I want to unmerge ssmtp and emerge sendmail, but I don't want to
break some dependencies on my system. In manual there is BIG WARNING
that portage does not check dependencies when unmerging...

Q2: How can I get list of all packages, installed on my comp, with
     their dependencies?

If you want you can enable the "mailwrapper" use flag, which enables
multiple MTAs to be installed at the same time. Then you just edit
/etc/mail/mailer.conf to switch which MTA to be used...

Or you just "emerge -C ssmtp && emerge sendmail" and everything should
be fine.

If a package needs to send mail it requires that there be a package 
installed that can do it. If you don't have anything installed this will 
default to ssmtp. However you *SHOULD* be able to to simply unmerge it, 
then emerge sendmail and it will work. If you are worried about it 
breaking things, just try a:
emerge -Duvp world
If it complains about wanting to install ssmtp again, then there is 
something explicitly depending on it. However if it is quite happy then 
it was a dependency on ssmtp, but rather a dependency that there be some 
way to send mail, and ssmtp is the simplest way to acheive that. While I 
doubt it, something may also have been linked against ssmtp, you can try 
a revdep-rebuild after you unmerge it. If there is anything broken it 
will complain and re-emerge the broken packages so they can be re-linked.
