Both watchdogs hardcoded the notification address. Read it from conf/watchdog.conf instead, matching the pattern used for the other credentials, so the repo carries no real contact details. If the config is absent the watchdogs still run and log; sendAlert notes the missing address and skips the mail rather than invoking mail(1) with an empty recipient.
