Description of problem:
After installing the stgit package with "yum install stgit", the "stg mail" command has only limited functionality.  It ignores the sendemail.smtp* settings and always attempts to deliver mail through the local host.

Local host delivery typically succeeds without error, but the mail items are then parked in the local system's mail queue forever if the local host is not configured to deliver mail.  No error message or bounce occurs.

Specifying --smtp-foo= on the "stg mail" command line seems to have the desired effects, but .git config file settings are ignored.

After installing the git-email package, full patch e-mail capabilities are available without requiring local mailer configuration, and configuration settings in ~/.gitconfig are respected.


Version-Release number of selected component (if applicable):
stgit-0.16-3.fc19.noarch
git-email-1.8.3.1-1.fc19.noarch

How reproducible:
100%.

Steps to Reproduce:
1. On a minimal install, "yum install stgit"
2. Set up sendemail.smtp* settings in ~/.gitconfig
3. Attempt to send patches with "stg mail --to=.... patch1 patch2"

Actual results:
The patches appear to be sent, but never arrive at the recipient.  Changing the sendemail.smtp* settings has no effect, but specifying --smtp-* command line options works.

Expected results:
Either the patches should be sent, or an error should be reported.  "stg mail" should use the sendmail.* settings specified in ~/.gitconfig or the local repository's .git/config file.

Additional info:
Adding a "Requires: git-email" in the stgit.spec file should address this.
