Alberto Bertogli d3396ace0b smtpsrv: Return a temporary error when we fail to check if a user exists

When we fail to check if a user exists, we currently return a permanent
error, which can be misleading and also make things more difficult to
troubleshoot.

This patch makes chasquid return a temporary error in that case.

Thanks to Thor77 (thor77@thor77.org) for suggesting this change.

It is designed mainly for individuals and small groups.

It's written in Go, and distributed under the Apache license 2.0.

Features

Easy
- Easy to configure.
- Hard to mis-configure in ways that are harmful or insecure (e.g. no open relay, or clear-text authentication).
- Monitoring HTTP server, with exported variables and tracing to help debugging.
- Integrated with Debian, Ubuntu, and Arch.
- Supports using Dovecot for authentication.
Useful
- Multiple/virtual domains, with per-domain users and aliases.
- Suffix dropping (user+something@domain → user@domain).
- Hooks for integration with greylisting, anti-virus, anti-spam, and DKIM/DMARC.
- International usernames (SMTPUTF8) and domain names (IDNA).
Secure
- Tracking of per-domain TLS support, prevents connection downgrading.
