Mail

This first tab is used to set system postfix and Cyrus settings.

Postfix

• My networks
  The list of "trusted" SMTP clients that have more privileges than "strangers". 
  Specify a list of network/netmask patterns, separated by commas and/or whitespace, for instance:

  Bloc de code
  127.0.0.0/8, 192.168.198.0/24

  For more information see  http://www.postfix.org/postconf.5.html#mynetworks. 

• Maximum message size
  The maximum size (MiB) of messages that users are allowed to send.

  Remarque
  Warning, this is the size of messages, not including the attachments they may contain. After files are converted to be attached to an email message, their size increases: allow for an extra 50% approximately. For example, if you want to allow attachments up to 10MB, you must set maximum message size to 15MB.

  Once the size has been changed, you must restart the IMAP proxy:

  Bloc de code
  service bm-ips restart

  Avertissement
  title Maximum limit
  The maximum size of messages handled by BlueMind can't exceed 100MB

• Relay
  Specify the address of the relay through which outgoing messages must pass.

Reverse Proxy

The "Reverse Proxy" tab is used to set:

• the password for the setup wizard set 's password generated automatically by BlueMind during installation.

  Astuce
  The logged-in administrator will not be asked for the old password, which means the password can be modified changed here in case it gets is lost.

• worker_connections: the maximum number of simultaneous connections that can be opened by a worker process.
  Un worker travaille pour une connexion, on compte donc One worker works for one connection, therefore worker_connections = nombre de connexions actives (ou susceptibles de l'être) en même temps. Soit le plus souvent number of (possibly) active connections at the same time. Most of the time, worker_connections = nombre d'utilisateursnumber of users.

  Astuce

  Afin d'adapter au mieux la valeur de ce paramètre, on pourra passer la commande sur le serveur afin de connaître le nombre de connexions actives à un instant T, en journée et en semaine par exemple In order to best adapt this parameter's value, you can run the command on the server to find out the number active connections at a given point in time, e.g. during weekdays: Bloc de code ss -p | grep nginx | grep -i estab | wc -l

EAS Server

The "EAS Server" tab gives you access to the Exchange Active Sync server configurations options, which handles mobile devices syncing.

• Allow unknown devices
  This option, which is disabled by default, authorizes any user to connect new mobile devices to their account. If the box isn't checked, authorizations must be validated individually for each user and device.

  Info
  When peripheral devices are associated to an account, go to the user's configuration panel in order to revoke them.

• Min/max push timeout
  Minimum and maximum intervals for push notifications to be sent to mobile devices.
  Users are able to configure this mode and be alerted of new emails automatically. The device no longer queries the server, the server sends information to their device instead.
