Subject of the issue

When bitwarden_rs tries to send emails via SMTP, not all errors will actually be recognised as errors.

Your environment

Bitwarden_rs version: 1.13.0

Install method: arch linux AUR package bitwarden_rs and bitwarden_rs-vault
Clients used: web vault
Reverse proxy and version: bitwarden (host A) <> stunnel (v5.56) (host A, self signed cert) <> nginx (v1.16) (host B, letsencrypt cert)
Version of mysql/postgresql: sqlite
Other relevant information: external SMTP server

Steps to reproduce

Started through systemd unit file from AUR package

Cause one of the following errors when sending via SMTP:

connection timeout
invalid TLS handshake (presumably that was a protocol/port missmatch)
invalid credentials

Expected behaviour

UI should tell the user that sending an email failed

Actual behaviour

Green notification pops up saying it was sent

Relevant logs
