Hi all, I have a Centos, Postfix, Amavisd, Spamassassin, MySQL setup and clean mail for quite a few domains.
One of these domains in particular is a remote site with their own Exchange 2007 server and they have asked me to allow TLS emails through, HSBC Bank is asking for this. I have looked around on how this works but so far I haven't found a clear explanation. I know that I need to setup postfix to receive the TLS emails, which shouldn't be a problem, and we need a verified certificate. I have also found that we then need to set up SASL to forward the mails onto the companies own email server and this is where I'm starting to get confused. Does anyone know how postfix/amavisd/spamassassin handles this and if it is at all possible? Do TLS emails bypass the spam checking or do I setup rules to lower the score if they are from this source? Any help would be appriciated. Mark
