I think haproxy can only do header manipulation with HTTP. In other words, rspadd will not work with mode tcp.
You should be able to have your PHP scrip add the custom header. Postfix can handle a lot of outgoing mail. If you don't mind me asking, I'm just curious how much mail are you sending out that you need to route it through a load balancer? Or is it more for redundancy of a multi-server to redundant mail gateway? > -----Original Message----- > From: boris17...@gmail.com [mailto:boris17...@gmail.com] > Sent: Wednesday, December 02, 2009 11:33 PM > To: haproxy@formilux.org > Subject: Load balancing PostFix Mail Out > > I'm currently trying to load balance balance Mailout from postfix MTA. > It work nice, but I have some "question" (maybe feature). > I want to add a "custom header" (this one is just after a test) but > rspadd seem to work only on http. > rspadd X-HAProxyRocks:\ Yes\0 > > Our mail sender is a php script.
