[pve-devel] [PATCH common v2 2/2] sendmail helper: allow empty display name in from

[Stoiko Ivanov]

This patch enables the sendmail helper sub to send emails with a non-existant
display name in the from address. This is used to replace the direct call to
the sendmail binary in pve-manager/PVE/API2/APT.pm.
