#Squirrelmail authenticated user password#

To fix this, create the file dovecot-lda.te with the following content: module dovecot-lda 1.0 One last thing is to make sure that on systems with SELinux running, Dovecot does not run into a permissions problem. (There may be easier ways to do this, but I have not researched that.)

#Squirrelmail authenticated user password#

Virtual users will be listed in /etc/dovecot/users, in the following format: actual password is generated using the command doveadm pw -s SSHA256, and must be copied-and-pasted into the users file. This completes the configuration of Dovecot. Ssl_key = squirrelmail authenticated user

The numeric values should correspond to the numeric UID and GID of the vmail account and group on your system.įinally, we need to configure SSL. This lets Dovecot figure things out (and, in particular, ensure that system users see their system mailbox, whereas virtual users have their inboxes under their user folders.)Īdditionally, still in /etc/dovecot/conf.d/nf, you need to specify the UID and GID of the virtual mail account: mail_uid = 1002

In /etc/dovecot/conf.d/nf, make sure that you have the following line: mail_home = /home/vmail/%d/%nĪlso make sure that you do not have a mail_location line specified. We now need to specify where mail is delivered. These lines are quite essential to ensure that Dovecot's local delivery agent (which will be invoked by Sendmail) can talk to Dovecot itself. Next, in /etc/dovecot/conf.d/nf, make sure that in the unix_listener auth-userdb section, the following two lines are present: user = vmail Without this, dovecot won't be able to figure out mailbox locations. Furthermore, still in in the userdb section, make sure to include override_fields = mail=mbox:~/mail This line ensures that a strong encryption method is used for storing Dovecot passwords. Next, in /etc/dovecot/conf.d/, make sure that the args entry in the passdb section reads args = scheme=SSHA256 username_format=%u /etc/dovecot/users These two lines allow Dovecot to recognize both system users and users whose identities are stored on a Dovecot authentication file. To begin, make sure that in /etc/dovecot/conf.d/nf, the following two lines are uncommented: !include

Our goal is to let Dovecot accept mail both for system users (who have UNIX accounts on the host) and virtual users, who may be using any one of several domains. So let us begin with configuring Dovecot. The target in my case is a CentOS 7 server configuration file locations are set up accordingly. I am assuming that Sendmail and Dovecot are installed on the target system. Google of course helped a great deal, but it didn't have all the answers. let's just say that on more than one occasion, I actually resorted to using the strace utility to find out what the devil is going on. Leave any one of them out, and things will just not work. Note that all of these steps are necessary.

An odd problem: Mail from system to virtual accountsĪnd it turned into an almost nightmarish obstacle course.

Set up the venerable sendmail server with the popular IMAP server Dovecot, using virtual domains.
