- This provides some information about the mailserver and if they are up or down.
- Will try to immediately re-send all mail that was previously deferred and sitting in the delivery queue.
To perform hostname, MX records and IP addresses of a domain
In your case, "hoststatus" would be useful since it will display the MX records and IP addresses near the bottom of the 'hoststatus' output.
Please enter the host or IP address to resolve. > neal-prince.com
Choose the query type: 1. A the host's Internet address 2. CNAME the canonical name for an alias 3. MX the mail exchanger 4. NS the name server for the named zone 5. PTR the hostname if the query is an Internet address,
otherwise the pointer to other information 6. SOA the domain's "start-of-authority" information 7. TXT the text information > 3
I noticed that there is a Time to Live (TTL) of 1 day for the hostname before it clears the cache. To immediately clear the DNS cache and have the Ironport AsyncOS go out and obtain current MX and IP addreses, type the following:
by the way, you can get a snippet of information on how the command works by typing,
help help dnsflush
Hmmm, the fact that your C100 is going to the MX 10 destination instead of the MX 5 one probably means that the MX 5 destination is down, since smaller MX values are more preferred.
But to answer your question directly, you can use an SMTP route to force the mail to go where you want it. Use the "smtproutes" command in the CLI.
