Sending emails via this protocol requires packages perl-Net-SMTP-SSL and perl-Authen-SASL, which we recommend, but they are not mandatory. Without these packages it is still possible to send emails to localhost and let the local daemon handle it (default behaviour). To fix this bug it was sufficient to install these two packages. Should we thus move them to requiremens to avoid further suprises? Thank you, Olaf, for cooperation in solving this bug.
