If I have a production mailserver and a series of Linux servers that

so many smtp servers installed on each of those boxes simply
forwarding mail as I choose to not have local delivery. Is there a
mechanism possible in CentOS to setup a pointer to a different
mailserver such that programs like mailx could still send mail?
Currently I have postfix setup with maps so that root on server A has
mail sent from [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> and that
is relayed to my production box. It just seems like it is an
additional service to manage on so many hosts?
Thanks!

There are lightweight SMTP clients that can be used as drop-in
sendmail(1) replacements by speaking directly to a remote SMTP server
instead of dropping the message in the local queue directory. One that
I've used is mini_sendmail
(http://www.acme.com/software/mini_sendmail/), though this was a while
ago but I seem to recall having some success with it.
Others have mentioned the trade-off between the additional complexity of
maintaining an MTA on each system and the fault-tolerance such a setup
provides, however, you can achieve similar levels of fault tolerance by
implementing redundancy on your relay server system(s). I guess it's up
to you to figure out what's appropriate to your environment.
