Virtual Hosts

Create a new virtual host

  • create vmail records in postgres for domain
  • create apache vhost configs
  • create let’s encrypt keys & config
  • create DNS A & MX records
  • create SPF, DKIM, & DMARC record

Let’s Encrypt!

Postfix

The domain to address system users is highball.org

SMTP Session

Some problems are easiest diagnosed by communicating directly with postfix

telnet mail.highball.org 25
HELO local.ylayali.net
MAIL FROM: kenneth@ylayali.net
RCPT TO: kenneth@highball.org

Subject: Test from telnet

Getting help on #postfix @ irc.freenode.org

20:44 < kennethd> !getting_help
20:44 < knoba> kennethd: "getting_help" : before asking your question, read the !relevant_logs and !showconfig factoids, and prepare a single pastebin containing all of 
               that data. if you don't understand what this means, or if you need help doing this, please let us know. also see !pastebin
20:44 < kennethd> !relevant_logs
20:44 < knoba> kennethd: "relevant_logs" : mail.* syslog Postfix log messages (NOT verbose, see !no_verbose) which show ONLY the entire handling of a single mail which 
               illustrates the issue with which you want help. Random selections from your mail log are not adequate. IMAP/POP3 daemons and external delivery agents often 
               log to the same syslog facility and should not be shown. Also see http://rob0.nodns4.us/postfix-logging
20:44 < kennethd> !showconfig
20:44 < knoba> kennethd: "showconfig" : when asked to provide your config, please provide a SINGLE pastebin (see !pastebin) with postconf -nf and postconf -Mf. if your 
               version is too old for those commands to work (< 2.9), you should upgrade, but see !showconfig_old
