Hi All, We have CentOS 6.2 running on our server, but since the only instructions for setting up Email with Postfix, Dovecot and MySQL in the Linode library (or on Linode's site) is for the configuration on CentOS 5 [ http://library.linode.com/email/postfix ... l-centos-5 ], I followed it for the installation/configuration of Email with Postfix, Dovecot and MySQL on our CentOS 6.2 Everything seemed to work fine until I got to the editing of the dovecot.conf file.. I replaced the content of the dovecot.conf file with stuff that the instruction asked to use to replace the dovecot.conf, but unsurprisingly, there were warnings. ...... ........

Additionally, we do not have a different version of dovecot.conf for CentOS 6. ..........if you're still unable to use email with this configuration, I would recommend reaching out to our user community for further assistance: http://www.linode.com/community/ " I would appreciate any help I can get here. Thanks in anticipation. [/quote] |

Hey, Recently ran into the same issue when setting up a new server on Ubuntu 12.04 (among others). The guide on the Linode Library provides instructions for Dovecot 1.x, while the newer versions of Ubuntu (and apparently CentOS) use Dovecot 2.x. The config file format has changed, so the one in the guide is no longer applicable. You can find the Dovecot 2 documentation here: http://wiki2.dovecot.org/ If you need help with the configuration, let me know and I'll do my best. You may also be able to install a Dovecot 1.x package, worth thinking about. It also looks like you need to install a package that provides telnet to test Dovecot. If it is working fine how it is, then I'd assume you should be able to go on as normal, but I suspect you won't be able to. It also looks like you have other problems with Postfix connecting to saslauthd, but there's not enough information to debug that issue. Could be related to your Dovecot configuration though. |

I would be surprised if there is not a telnet client included with your distro. You should not need to install telnet to use the client to test services on your server. |

Dear redhat19, I suggest you try iRedMail solution to build a full-featured mail server in one minute instead of build it yourself. iRedMail is a FREE, full-featured mail server solution, it works pretty well on Linode VPS. http://www.iredmail.org/ |

Sniff . . . . Sniff . . . . Smell that? Smells like spam. ZhangHuangbin, you've made two (and only two) posts, both hawking iredmail. Visiting it's site, it's hardly free. If you want anything but the barest of installs you need to pay $299/year or $599 for a lifetime license, just to get a bunch of open source apps bundled into a single binary installer. Instead of trying to sneak it in, man up, and just put your product in your sig file. |

Hi all, Thanks for all your response. @Jerzzp: Yes, I had to install telnet. and as per the instrucions on http://library.linode.com/email/postfix ... l-centos-5 The next step is to test Postfix with the telnet command. "You should see output similar to the following: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 plato.example.com ESMTP Postfix ehlo localhost 250-plato.example.com 250-PIPELINING 250-SIZE 30720000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN 250-AUTH=PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN " but here's what I see on my end: [root@myserver1 /]# telnet localhost pop3 Trying ::1... Connected to localhost. Escape character is '^]'. ehlo localhost ..and nothing else. Does this mean Postfix is not working or something is wrong with the configuration? Response from Linode Support: Hello, If Postfix is running, there may be a problem with your configuration. Unfortunately, we cannot assist with specific configuration issues; for further assistance, I would recommend reaching out to our community: http://www.linode.com/community/ Regards, So, guys I would appreciate any help I can get with building the configuration files for Devcot 2.x as @Jerzzp has pointed out. Thanks @ZhangHuangbin Thanks @vonskippy and thanks to @Dweeber |

Postfix runs on port 25, and does not listen to POP3. Try 'telnet localhost 25' to test Postfix. POP3 has an entirely different dialogue. |

Alrighty I'll post the Dovecot config files I use, but I won't be able to until later this evening. I also use a split file configuration, but it works. If you could maybe remove and reinstall Dovecot to get the default config file, because mine is based off of that. |

Like I said you're probably gonna want to completely remove and reinstall Dovecot so your config files aren't all jumbled. The files I have are just the default files (but for Ubuntu 12.04) modified to make this configuration work. YMMV. /etc/dovecot/dovecot.conf (via doveconf -n): Code: # 2.0.19: /etc/dovecot/dovecot.conf Then in /etc/dovecot/conf.d/auth-sql.conf.ext: Code: driver = mysql |
