Supported Mail Server Combinations
Tequila is a toolset for administration tasks on a Postfix mail server.
The Tequila suite is written in the Perl programming language.
It comes with its own, built-in web server, which handles all
communication with the client browsers (completely SSL encrypted and
Currently, Tequila supports three types of mail server software combinations:
- Postfix & Cyrus-IMAP/SASL
- Postfix & Courier-IMAP & OpenLDAP
Tequila allows you to perform the following tasks:
- Create, edit and remove virtual mail domains.
- Create/edit/remove mail accounts (POP3 and IMAP).
- Create/edit/remove aliases to mail accounts and mail distribution lists.
- Virtual domain administration can be delegated to several domain
- Local domain admins may be confined to work within their own domains only.
- Users can configure their automatic mail forwarding and out-of-the-office notifications when they are on leave.
- Out-of-the-office / forwarding services can turn themselves on and off if required.
- Email account passwords can be modified by the users themselves.
- Users can choose their preferred language from the list of available choices.
- Separate languages can be in use at the same time by the Tequila admin, the domain admins and the various users.
- Tequila's on-screen messages can be translated online - no programming skills required.
- SASL accounts/passwords are kept in sync with the Tequila accounts
(SASL version 2).
- Special mail accounts may be created to run arbitrary
embedded backend scripts on incoming emails. Tequila ships with a
"detachmail" script, which can split off specified attachments by name
and transfer the recoded files to a ftp server. This also includes
sending automatic status notifications to the sender and to a circle of
ftp server admins.
is required that you use one of the following mailserver software
combinations (either POP3 or IMAP) to deliver the emails to the mail
account holders on your server:
Should be obviously (and already present on most systems).
Postfix is a Mail Transport Agent (like Sendmail, Exim, Qmail and others).
It has some nice, clean features for virtual domain declaration and
is very flexible in managing different virtual domain files.
VM-Pop3d is a POP3 daemon, which can be used as a replacement for
"qpopper" or similar programs. Use this little daemon and throw away your
unix user accounts, which are nessesary for "normal" POP3 daemons.
Instead, extract your old pop3 user accounts from the /etc/passwd file
and store them under a virtual domain directory structure for use of
Very easy to install/maintain if you simply need some (hundreds) pop3
accounts, e.g. in your company.
combination works in a fashion that postfix hands over incoming emails
to cyrus-imap, which then stores the email in a maildir-style
directory. Cyrus then uses the SASL library to identify incoming requests
to access emails stored in these directories.
This is one of the possibilities
to set up an IMAP based mail server, but one that is definitely more
complex than a POP3 server variant.
With this combination it is
possible to configure postfix to store incoming emails in a
maildir-style directory tree, which is also used by the courier server
to access these emails by the users. All relevant data for all parties
is stored in a LDAP directory (accounts, aliases, passwords, etc.),
which allows very fast access and can be also used by any other
This is a very interesting variant if you want to implement an IMAP mail
server, but is comes along with the disadvantage of the hardly to
understand storage concept LDAP. Recommended only for experienced
