I just tried to set up a mail server on my Ubutnu 14.04. The goal is to be able to send mails from info@mydomain.com and receive mails sent to the same adress.

Now I followed this tutorial to install Postfix, Dovecot and SquirrelMail. I followed the tutorial and everything worked fine. Additionally, I added my info-user to the mail-group and as well, I set an MX-Record from @ to @, so as host, everything is sent to my domain. I found this as one problem of somebody else, which fixed it for him.. For me, it doesn't change anything though.

Now the web-part of SquirrelMail works fine, I can click everywhere and compose mails. Sent mails also are in the SENT-Folder.

However, I do neither receive mails on SquirrelMail, nor do I receive mails on mail accounts, where I tried to send mails from SquirrelMail. I tried 1and1, web.de and gmail... All with no results...

I checked the var/log/mail.err with no result.

But: in mail.log, there are some interesting lines, I'm just gonna paste them in here:

Note that I replaced the real adresses with pseudo-adresses.

To be honest, I don't really know about the errors, but I think messages like NOQUE: reject, Relay access denied or status=deferred (host mx-ha02.web.de[212.227.17.8] refused to talk to me: don't look really good.

Does anybody have an idea on what I'm missing or what I should fix?

You have (at least) two distinct issues here:

First, you can't receive mail with the error Relay access denied. This means that Postfix is not configured to receive mail for your domain name.

To fix the problem you will need to reconfigure Postfix, e.g. with dpkg-reconfigure postfix and give it the correct domain name. It appears that Postfix was set up with the name localhost.localdomain instead of chatxpress.com.

Second, you can't send mail because, according to the error messages you received, your host's IP address does not have a PTR record. I was able to confirm this:

$ host 85.93.24.159
Host 159.24.93.85.in-addr.arpa. not found: 3(NXDOMAIN)

The PTR record must be set by the owner of the IP address, that is, the datacenter hosting your server. Contact them for further information on how to set your PTR record.

  • Thank you for the answer! I just contacted my hosting provider regarding the PTR-record. Regarding receiving mails, I tried to reconfigure it, but I still can't receive any mails. But there were many points to configure..I used "Internet Site", "chatxpress.com" as System Mail name, "info" for root and postmaster mail recipent, and for "Other desitnations to accept mail for", I just left the list, as is it (so myhostname, localdomain, localhost, localhost.localdomain, localhost)..Then i pressed no regadring synchronous updates on mail queue ---> the rest in the next comment – nameless Jan 13 '19 at 17:13
  • for postfix configuration on local networks, I also left it, as it is, so: 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128... I pressed no to not use procmail for local delivery, used 0 to have no mailbox size limit and chose to use all internet protocols (ipv4 and ipv6) are there any prolems in the configuration...? – nameless Jan 13 '19 at 17:15
  • Okay, I got it fixed! somehow the `dpkg-reconfigure` didn't work properly, but manually setting the hostname in `etc/postfix/main.cf` seems to have worked! – nameless Jan 13 '19 at 17:38
