If I have a production mailserver and a series of Linux servers that all develop mail from logging etc, it seems slightly redundant to have 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 root@xxxxxxxxxxxxx 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.

cheers
