Overview Message filtering is done prior to delivery via maildrop. Each message goes through two levels of filters: (1) global — processed first in /etc/maildroprc followed by (2) local per-user filters in $HOME/.mailfilter. Basic filtering recipes are provided below. Syntax and usage may be found in mailfilter(7). Important: on older…
Overview A hostname, combination of optional subdomain and mandatory domain, may be configured to act as an e-mail domain, ie. receive e-mails on that host. These hostnames are added via Mail > Mail Routing. For any domain present there, the server will act as the final destination bypassing MX lookups. This…
Overview Sometimes an e-mail sent from the server to a recipient will fail. There are a variety of causes and as a “best practice”, the receiving side will report the failure reason for easy understanding. However, it is prudent to note that a reason is not mandatory (just good practice)…
Your IP address, which is the location of your account, may be found within the control panel under Account > Summary > General > IP Address.
Overview DNS maps a hostname (comprised of a domain name + optional subdomain, e.g. example.com or www.example.com) to an addressable machine (by IP address) somewhere on the Internet. DNS works by issuing multiple queries, recursively, until the machine address is resolved. Process Initial query Of a most trivial example, let’s assume…
Overview Often times when switching hosting companies we would like to see what your domain name looks like before finalizing DNS changes by changing nameservers. Overriding DNS is done through a HOSTS file. Any entry in a HOSTS file overrides any other DNS setting that is resolved by a nameserver. Making Adjustments…
DNS propagation may take anywhere from 15 minutes to 24 hours. In rare circumstances, propagation may take longer. Propagation begins once the nameserver settings are changed through the domain registrar, which is the company through which you purchased your domain name. Explanation DNS maps a hostname, e.g. apnscp.com to an…
In general, allow for 24 hours for DNS to fully propagate. This window may be reduced to 60 seconds or less following proper procedure. You need a fair understanding of DNS records and roughly 5 days to complete the process with minimal downtime. Steps Setup the account with Lithium Hosting, but keep…
A nameserver controls what servers will handle DNS for your domain (domain to IP mapping). Nameserver settings for your account with us are ns1.lithiumdns.net with the IP address 104.238.162.214 and ns2.lithiumdns.net with the IP address 45.77.110.160. It is recommended that you use our nameservers, so you can take advantage of…
