I have been considering sending the email to google for relay, but is this even an option? Do we need to implement outgoing spam filtering? Hello Al, This is a technical mailing list for the Postfix MTA. If you have a question about managing your Postfix server we'd be glad to assist. If your question indeed relates to your Postfix server, please provide information from your UNIX mail log file that demonstrates emails are not being delivered.

Re: Loadbalancing+failover solution
Hi list, Robert: thanks for your quick reply. Sorry for being vague - This is for internal outgoing mail only (my linux servers-my postfix relay server-ISP mailserver). I would like loadsharing (maybe real balancing is not needed for me...) between my linux server-my postfix relay server. My guess is I could do this (atleast) 2 ways: 1. DNS RoundRobin 2. MX with equal weight Any thoughts: e.g. will mail actually retry delivery for all IP's listed in DNS RR if one is not responding, or will it just directly return to sender=local linux user without trying any of the other IP's...) ?

Re: Need help setting up Postfix
Check dyndns it helps with mx records, its not free but is the cheapest solution that I know. Its about 1 usd or something like that. Then you set up you domain which is a subdomain of their own (yourdomain.dyndns.com or something) and it changes everytime your ip does. You just need to install a client. I hope this helps.

Re: Need help setting up Postfix
As far as I know and may be Im wrong the mail server looks for the mx record, if it doesnt find one it looks for the A record. You just need to enable the dyndns pro (its the cheap one). You may try with just the A record dont pay anything just set it up and test it, you have nothing to loose right? Saludos Ing.
