The update breaks the way Bootmail (and probably quite a few other scripts) constructs its mail messages. Currently it looks like this:
print_mail_text | sed -e "s/[^[:print:]]//g" | rootsign | mail -s "$subject" "$recipients" -- -F "Bootmail" -f "$FROM_MAIL"
The part after "--", i.e. the switches -F and -f, is now no longer supported by bsd-mailx and results in "bad address syntax" error messages in /var/log/mail.log:
To fix this in Bootmail I propose using the "-a" commandline switch to set additional mail headers. Something like this:
print_mail_text | sed -e "s/[^[:print:]]//g" | rootsign | mail -s "$subject" -a "Bootmail <${FROM_MAIL}>" "$recipients"
This has the advantage that it works with (probably) all bsd-mailx versions and most other mailx variants as well, including those that never supported specifying sendmail options.
bsd-mailx recently had a security update that completely removes support for specifying classic sendmail options after "--" on the command line. See http:// changelogs. ubuntu. com/changelogs/ pool/main/ b/bsd-mailx/ bsd-mailx_ 8.1.2-0. 20111106cvs- 1ubuntu0. 1/changelog for 8.1.2-0. 20111106cvs- 1ubuntu0. 1. This is on Ubuntu 12.04.

I reported a bug against bsd-mailx in https:/ /bugs.launchpad .net/ubuntu/ +source/ bsd-mailx/ +bug/1414684 because this change is obviously quite troublesome for any script that relies on mailx understanding sendmail options.
To fix this in Bootmail I propose using the "-a" commandline switch to set additional mail headers. Something like this:
