Subject: [PATCH] fix(vikunja): set pod FQDN so SMTP EHLO passes Stalwart
 validation (DEV-563)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stalwart's port-25 relay rejects bare EHLO labels — needs at least one
dot. Vikunja doesn't call go-mail's WithHELO, so it sends
os.Hostname() as EHLO. Setting hostname/subdomain plus
setHostnameAsFQDN=true makes the pod's kernel hostname a valid FQDN
(vikunja.basicstack.vikunja.svc.cluster.local), which Stalwart
accepts.
