SMTP (Simple Mail Transport Protocol) is the on-the-wire language that email systems use to send messages to each other. While mail is being transmitted, there are a number of reasons why the other server might disconnect: network outages, the remote server crashed, etc. If for any reason the session is disconnected, you will receive this message. There is no need for you to take any action.

There are two reasons why you do not see an immediate reduction of disk utilization when you delete messages from a Citadel system. The first reason is that deletion of messages is one of a number of operations which the Citadel server defers for later processing in order to keep interactive performance running smoothly and quickly. The messages you delete will appear to be gone, but they are actually still in the database. When the nightly auto-purger job r… Wed, 03 Sep 2008 23:15:34 -0400 http://www.citadel.org/doku.php/faq:systemadmin:error_creating_new_user?rev=1196652153 If you are attempting to administratively create a new user, and you see one of the following error messages: * User accounts are not created within Citadel in host authentication mode. * You are attempting to create a new user from within Citadel while running in host based authentication mode.

The way out of this situation is to rerun /usr/local/citadel/setup or in debs / : /usr/lib/citadel-server/setup and enter a new / existing user you know the password to. The next time this user logs in, he will be granted aide privileges.

Quite simply, they are configured by adding those addresses to the user's vCard. If you are editing the user's address book entry using the admin utilities in WebCit, simply enter one or more addresses. Any addresses that are in one of your registered domains will automatically be honored for incoming email. Furthermore, if any addresses exist in a domain which you have declared a 'directory' domain, the user can receive email o… Sun, 31 Dec 2006 13:25:17 -0400 http://www.citadel.org/doku.php/faq:systemadmin:how_do_i_disable_sendmail_on_freebsd?rev=1168765705 If you're using FreeBSD 6.0, you can control sendmail very easily by adding variables to your /etc/rc.conf file.

It is likely that your Citadel installation will outlive the hardware on which it runs. We have made several options available for migrating Citadel to new hardware. Citadel stores its data in a binary, architecture-specific format. As a result, you can only make a direct copy of the binary files in the byte order and byte alignment are identical on the old and new hardware. So, for example, if you are moving from SPARC to Intel, or… Sun, 02 Aug 2009 16:05:57 -0400 http://www.citadel.org/doku.php/faq:systemadmin:how_may_i_improve?rev=1234295919 In a very large or heavy-use environment, you can improve the performance of Citadel's data store by placing the databases and/or database logs on a separate disk, or disk array. This is very easy to configure. Here are the required steps.

When you initially install the system, a private key and self-signed certificate are automatically generated for you. However, you may wish to purchase a certificate signed by a recognized certificate authority. Alternatively, you may wish to have a certificate that is self-signed, but has the correct Distinguished Name (DN). If you wish to do either of these things, here are the required steps.
