[Reportbug-maint] Bug#761931: reportbug: bogus "not fully qualified" with ssmtp

[Eduard Bloch]

Package: reportbug
Version: 6.5.1
Severity: normal

Dear Maintainer,

I am trying to send bugreports from a laptop with a "nomadic" network
connection. Therefore, I have a configured ssmtp here which runs over an
adhoc SSH tunnel and this works fine... with everything but reportbug.
Example:

Report will be sent to "Debian Bug Tracking System" <submit at bugs.debian.org>
Submit this report on broadcom-sta-source (e to edit) [Y|n|a|c|e|i|l|m|p|q|d|t|s|?]? 
Sending message via /usr/sbin/sendmail...
sendmail: RCPT TO:<ed at idefix> (554 5.7.1 domain idefix of <ed at idefix> is not fully qualified.)
Error: send/write operation failed, bug report saved to /tmp/reportbug-broadcom-sta-
source-20140916-6501-gCHq86
$ /usr/sbin/sendmail submit at bugs.debian.org < /tmp/reportbug-broadcom-sta-source-20140916-6501-gCHq86 

So this should work just fine. What does it do to sendmail to make it behave
that way? The manual page does not tell me anything sensible WRT such problems.

Regards,
Eduard.
