Trying to remove any MTAs from my system, so I did an emerge -C ssmtp,
which unmerged it just fine. But, doing a emerge -DNtpvu world
returns:

mark@laeb ~ $ sudo emerge -DNtpvu world

These are the packages that I would merge, in reverse order:

Calculating world dependencies ...done!
[nomerge ] x11-terms/xterm-200-r3 -Xaw3d -debug -toolbar
+truetype +unicode
[nomerge ] sys-apps/utempter-0.5.5.5-r1 -debug
[ebuild N ] mail-mta/ssmtp-2.61 +ipv6 -mailwrapper -md5sum +ssl 0 kB

Total size of downloads: 0 kB
mark@laeb ~ $

I assume either xterm or utempter is requiring ssmtp, but I don't
understand why. Any ideas?

> Trying to remove any MTAs from my system...

Normal unix OS's require an MTA to be defined. Portage has virtual mta
placeholders that define the MTA that is installed on the system (i.e. I'm
using postfix).

If you don't have an MTA installed (which you don't), portage knows that the
MTA is missing and wants to install ssmtp as the default mta.

The question I have is why would you want to remove all MTAs?

Looking at the ebuilds themselves, neither ebuild has a dependency
upon ssmtp or an other mta.

Its a virtual dependency.

ssmtp is not really an MTA, but a wrapper for a script that emulates
sendmail. Its harmless and uses very little space so you should keep it
(besides, you might need it if you want output from cron scripts emailed
to you).

A. Khattri,

Ah yes, I remember reading it's not a full-fledged MTA. I was just
curious as to why it was trying to install. And to answer the first
reply's question: "The question I have is why would you want to remove
all MTAs?". Why have something on your system when you don't use it?
This is a personal server; I have ssh setup, I check the log files
myself.

My reason,

Disk space is too cheap to waste time keeping a small tiny place-holder
MTA inactive... The fact you and others have emailed about this has
already not been worth the cost in disk space... Wink

Yep, that's probably it. I ran into this a while back. Unfortunately equery is unreasonably slow with such queries. The fastest way I've found: find /var/db/pkg -path '*DEPEND' | xargs grep virtual/mta

Yeah, that's what it is.
