[pve-devel] [PATCH guest-common 1/4] vzdump: loosen mailto pattern to allow whitespaces

[Fabian Ebner <f.ebner@proxmox.com>]

to make it more compatible to what we had previously. In pve-manger,
split_list() is called on the parameter, so any whitespaces and even stand-alone
',' and ';' are taken care of, leaving only the real addresses. This also fixes
creating a backup job with empty mailto in the UI.

For example,
> vzdump 153 --mailto " ,,,developer@proxmox.com; admin@proxmox.com ; "
was valid and worked in PVE 6.2.
