In mail.log zie ik "warning: hostname localhost does not resolve to address ::1: No address associated with hostname".
Ik gebruik postfix als relay server. Met fetchmail ontvangen ik van verschillende providers mail. Dovecot gebruik ik als imap tool. Verzenden en ontvangen van mail gaat helemaal prima.
Waar komt deze warning vandaan, en hoe kan ik er voor zorgen dat ik die niet krijg? Ik begrijp het zelf niet zo goed.
