The CentOS document http://wiki.centos.org/HowTos/postfix explicitly says that its instructions may not work in CentOS-6. Does anyone know of reasonably simple postfix documentation for CentOS-6?
no. Maybe you can write one after you figure it out :-)
I'll be happy to suggest a modest addition to http://wiki.centos.org/HowTos/postfix when I have found why my from address was set to ------------------------------- tim@localhost.localdomain MAIL FROM domain does not exist (in reply to MAIL FROM command) ------------------------------- As I have said, I gave my fqdn in every place I can think of.
Postfix's target audience is not the average joe user but e-mail administrators. It is assumed you know some stuff about how smtp e-mail works.
I wonder if that is, or should be, any longer the case? I would have guessed that many, perhaps the majority, of CentOS users are now running home networks rather than commercial sites. I realise that RedHat may not be particularly interested in these people, but I would have thought CentOS should be.
For simple scenarios, you go to the 'General configuration' bullet points. In there you even have standard configuration examples:
http://www.postfix.org/STANDARD_CONFIGURATION_README.html
Once you have that figured out, then you can go on to other configs, like the content inspection, integration with other data sources, performance problems, etc. It does make sense once you approach it with an e-mail admin hat on.
I'm not an "email admin" except by necessity. If in fact it takes say two days of reading to setup postfix then I would revert to sendmail, which has been working perfectly for me for years. (Incidentally, having now setup postfix/amavis/clamd/spamassassin it does not seem to me to have any advantages - at least in my case - over sendmail/procmail/spamassassin . I've been told it is much better, but nobody has told me why.)
But as it happens, two short documents, http://wiki.centos.org/HowTos/postfix and http://www.cyberciti.biz/faq/postfix-smtp-authentication-for-mail-servers/, told me everything I needed to set up postfix on a home network. If I had homed in earlier on these two documents it would have taken me 20 minutes or less to set it up.
If what you want is an appliance that handles this stuff but hides it all under the hood from you,
I don't; I just want to be able to continue to send and receive email as I have been able to for years.
maybe you should be looking at commercial offerings like barracuda. It is nothing to be ashamed of to buy stuff that works and has support when something goes wrong. Handling e-mail for a company without understanding how it works internally can be stressing.
As I have said, I am not a company. I think I run a fairly typical home network, a setup that I would guess is going to become steadily more popular as the number of devices on a local network in the average household grows: laptops, TVs, smart phones, printers, etc.
Also, the postfix mailing list is the best place to ask postfix questions
I did ask the same two questions on that newsgroup/mailing-list and got no response. As you say, it seems to be the haunt of commercial or company email admins.
