I've got a couple of configuration problems with email on a CentOS machine, and I don't nderstand what the errors are telling me. A quick check on Google just made things worse (apparently, several things can cause these errors.) So I'm looking for advice on how to track these things down and fix them. Here's what I'm seeing tn the logs:
Jan 9 10:22:22 oneimage postfix/smtpd[19511]: fatal: No server certs available. TLS can't be enabled Jan 9 10:22:23 oneimage postfix/master[7667]: warning: process /usr/libexec/postfix/smtpd pid 19511 exit status 1 Jan 9 10:22:23 oneimage postfix/master[7667]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling These repeat excessively. What I was trying to do was configure Postfix / Dovecot so that when I go to pick up my mail it is encrypted first. So I set the SMTP server to use "normal password" and SSL/TLS protocol on port 465. I don't think it's really asking for breath mints, so what's it talking about "certs" for? I think this is CentoOS 6. Anyway, Postfix was the default, not Sendmail. Another problem (which is probably related) is that the machine I call in on and use to upload my email for delivery, gets it's IP via DHCP. But the IP that I'm assigned comes from Verizon, and they draw from a rather large pool of IPs. The range of potential IPs that I might be assigned even crosses class B networks. One hour my IP might be 75.220.34.136 and the next time it might be something completely different. In any case the possible range is large. So what would I use for $mynetworks in main.cf so that I can allow relaying for my outgoing email?? Or for remote devices using DHCP, do you use another strategy to permit them to send outgoing mail? I have no problems sending out email from my local network, so I'm pretty sure that I've got things partly right, but how do I tell the smtp server how to recognize me even if I might be using any IP in say, 75.192.0.0/10? Because if I put 75.192.0.0/10 in $mynetworks, that seems like a pretty wide filter and doesn't give me the security I want. Or am I totally confused on what's actually going on? (I'm pretty new to the whole subject of email transfers.) Any help would be appreciated. I'm not getting anywhere on my own with this. If you need to see some log records or config settings Just tell me what you need to see and I'll post it.
