David: I double-checked and it turns out that the SMTP port *is* open on my iptables configuration. I don't know how it opened (maybe postfix did it) because I'm positive it was closed at the time I finished installing FC5 on the system. At that time I went in and opened 80 and 22, which is why I initially said only those were opened.
Out of curiousity I shut the SMTP port, and sure enough, mail was no longer getting through *to* the server. (I was still able send mail out to other domains.) Receive capability was only restored when I opened the port again and rebooted. That having been said - do I need to worry about open relays or not? I would think *not* because I edited the Postfix's main.cf to "only forward mail from the local machine." In your opinion, did I go far enough? My other question concerns Dovecot. I went ahead and reviewed the linuxmafia site as suggested, along with some various sites about Dovecot that Google brought up. Nonetheless, I can't seem to figure out exactly what, if anything, I'm supposed to do to enable Dovecot as an MDA. I went ahead and modified the startup configuration so that Dovecot starts on boot (and indeed, it is listed among root's running processes) but the primary Dovecot website insists that little if any configuration is needed for a system like mine. Further (and forgive me if this sounds really dumb), the configuration file and the (online software documentation) aren't clear on whether or not I need to remove the # from the lines containing configuration directives. First it says that any line preceded with # is a comment line and is ignored. Then it says "It is not necessary to remove # from the beginning of a directive line." Huh? Which is it? Any other daemon I've worked with (like Apache) required me to remove # from the start of a line in the config file, if I wanted the daemon to be able to read it. I haven't even touched Squirrelmail yet because it was my understanding that it won't work unless Dovecot is configured correctly.
