we have two mail servers and want to setup failover for DR.
we have a line in sendmail.cf like this
and this works fine......
we changed it to
Code:
DS smtp1.domain.com smtp2.domain.com
this is bad, we get errors of savemail panic and many bounce messages and such. the errors say cont find server smtp1.domain.com.smtp2.domain.com
our two solutions to the problem are
version 1
Code:
DS [smtp1.domain.com] [smtp2.domain.com]
version 2
Code:
DS smtp1.domain.com:smtp2.domain.com
both seem to work but I assume that one is more correct than the other.
looking for some education as to what the diffcence is.
