Package: apticron
Version: 1.2.5+nmu1
Severity: normal
In the Mailx() function of apticron, if the mailx binary is neither
heirloom-mailx/s-nail, then mailx is used with the -a option to override the
email sender address.
At least with bsd-mailx doing so will only change the From in the mail header
but not the From of the enveloppe. Using -r in needed to override the envelope
On systems with a minimal mta configuration to send outgoing emails, this is
likely to cause email delivery problem as the enveloppe will be
r...@hostname.fqdn and might be rejected by the remote mta if hostname.fqdn
doesn't actualy exists.
Extract from bsd-mailx man page:
-r from-addr
Use from-addr as the from address in the message and envelope.
Overrides any from options in the startup files.
So I would suggest to use -r instead of -a when bsd-mailx is the mailx binary,
as it's done when it's heirloom-mailx/s-nail, to improve deliverability.
