Something about DNS!


If I,ve set two MX records for two different machines on the same domain with the same preferences number (let say... 10 for each record of them).

How the incoming and outgoing messages will be proceeded (i,e, which machine will receive/send the email for the domain)?

Here's what O'Reilly's DNS & Bind book has to say about it:
Quote:
More than one mail exchanger may share the same
preference value, too. This gives the mailer its choice of which to
send to first.[1] The mailer should try all the mail exchangers at a given
preference value before proceeding to the next higher value,
though.

[1] The newest version of sendmail, version 8,
will actually choose randomly among mail exchangers at the same
preference.

There was a similar question to this one raised a little while ago. I think that one solution was to have both mail exchangers spool to the same share NFS file system, although this introduces a single point of failure again

Have a search for mention of mail servers in the last 3 weeks.
