Installing Mailserver on FreeBSD 10.2

Hello Guys,

I tried to install a simple mailserver on my FreeBSD 10.2 following this tutorial:

https://www.vultr.com/docs/simple-mailserver-postfix-dovecot-sieve-freebsd-10

But at the last step I get the following error:

Code:

And I don''t know how to solve this problem. Can someone give me a hint or help me? Additionaly does someone know how to implement MySQL to create / delete user via database?

Greetings
 
Looks like you skipped this step:
The next step is to assign the correct path for your users' mailboxes in the same file, under the mail_location directive:

But what did iI wrong there?
I looked into the file and there was mail_location = maildir:~/Maildir the same as in the tutorial.
 
Ok iI checked the file and the settings are correct.
still get this error

Ok. Now I can send and receive emails.
But how can I install a newer version? I fetched my package, isn't it the newest version then?
 
I would like to use my own mailserver. But I'm not sure if iI can use this server because iI want a secure mail server. Is this setup ready for productive use ?

First, you installed Dovecot v1.x which has been tagged by the Developer as being obsolote, see: http://dovecot.org/documentation.html. This doesn't necessarily mean that it is highly vulnerable, however, the term "obsolete" is a warning at least to me, that security fixes for Dovecot v.1.x have a lower priority than those for Dovecot v2.x.

Second, Dovecot in your installation utilizes actual system users. This is OK, if this is for serving e-mail for you and you family, i.e. for people that you can trust as you can trust yourself. If you use Dovecot with system users for third parties, then you are urged to build in all your security considerations into your system user database. For this reason, in general, I prefer to setup Dovecot with virtual users, because this choice already prevents a mail user gaining accidentally access to other resources on my mail server.

Third, the default TLS settings are quite unrestrictive in terms of protocol and ciphers to be used. This may be a security risk as well.

Sometime ago, I wrote a series of articles in the Howto section of this forum: Home Mail Server with TLS and non-Plain authentication.

It describes utilization of Dovecot v2 + Postfix with a simple file based virtual user setup. It is quite lengthy, and perhaps it might be a somewhat boring reading for people who don't want to get explained all the bloody details. At least, it might give you an idea on what to look out for, when it comes to security.
 
Much thanks for your informative answer. Its not boring iI will read it. Because I want a secure server. Thanks.

Yes definitely, I have this system running with 10.2 now. You even won't need to install OpenSSL from the ports, since v1.0.1 is part of the base system, and all the modern ciphers and TLS v1.2 is now implemented.
