Why is sendmail slow?
Raw
gistfile1.txt
https://linuxconfig.org/sendmail-unqualified-hostname-unknown-sleeping-for-retry-unqualified-hostname
Operating System: Linux Solution: sendmail is searching for a FQDN ( fully qualified domain name ). In our case the host name is "debian" and that is not a FQDN. To resolve this problem change /etc/hosts: FROM:
127.0.0.1 localhost
127.0.1.1 debian
TO:
127.0.0.1 localhost.localdomain localhost debian
127.0.1.1 debian
