General Settings
To access the general settings for SmarterMail server, click the settings icon
and click General Settings in the navigation pane. The general settings
will load and the following tabs will be available:
Server Info
Use this tab to specify the following server settings:
- Hostname - The hostname of the server. Note: Hostnames should be in the
format computername.domain.com.
- Postmaster Mailbox - The email address for the postmaster. This is usually
the owner or system administrator.
- IP of Primary DNS - The IP address of the primary DNS server. If left blank,
the DNS server information will be pulled from the the Windows Networking settings
(recommended).
- IP of Secondary DNS - Enter the IP address of the secondary DNS server. If
left blank, the DNS server information will be pulled from the the Windows Networking
settings (recommended).
- Logout URL - The URL to which users are redirected upon logout.
- Enabled - Select this checkbox to redirect users to the Logout URL after
logging out of SmarterMail.
- Enable domain admins to override logout URL - Select this option to allow
domain administrators to specify the Logout URL. If this option is not enabled,
it will not be visible to domain administrators.
Spool
Use this tab to specify the following spool settings
- Spool Path - The full path in which messages are stored prior to delivery.
If you are using a real-time virus scanner, this is the path that must be scanned
in order to properly handle viruses.
- SubSpools - SubSpools are within the spool path and allow SmarterMail to
work around the NTFS limitation of 30,000 objects in an individual folder. SmarterMail
will utilize subspools by allocating up to 10,000 messages per subspool. (Default
is 10)
- Delivery Delay - This number of seconds mail will be held in the spool before
it is delivered. A delivery delay is beneficial when you are running a secondary
service (such as a virus checker) that needs access to messages prior to delivery,
as it provides ample time for the secondary service to interact with the message.
By default, the delivery delay is 15 seconds.
- Retry Intervals - When the mail server is unable to contact the receiving
server, the email attempting to be sent is held for a period of time before attempting
to be resent. This is the time between retries. Users can specify multiple retry
attempts to resend emails before it is bounced. By default, this is set to 4 attempts
- at 15 min, 30 min, 60 min, and 90 min intervals.
- Attempts before bouncing DNS errors - The maximum number of attempts SmarterMail
should make before the message is bounced due to a DNS error. The most common cause
of a DNS error is a misspelled domain. Limiting the number of attempts before DNS
errors are bounced is beneificial because messages will not sit in the queue for
long periods of time processing unnecessary messages and possibly slowing the system
down. This will be helpful to users because messages will be bounced sooner and
will give users the opportunity to fix any mistakes and get a message resent. By
default, the server will make 2 attempts. Note: Setting this at 1 retry can be dangerous
if the DNS server fails or if there is a loss of Internet connectivity. To disable
this feature, set the number of bounces equal to the number of retry intervals.
- Command-Line File - Enable this and enter the full path to an executable
you wish to use to process incoming messages. Use %filepath as an argument to pass
the path of the email file to the executable. It is allowable for the executable
to delete the message to prevent delivery. Example: If you set this field to "c:\program
files\myexe.exe %filepath", the program myexe.exe will be launched with the full
path to the spool file as its first argument. Note: The command will not be executed
if the Enabled box is not checked.
- Command-Line Timeout - The number of seconds that the server will wait for
information from the remote server. In general, a timeout of 5 seconds should suffice.
Reports
Use this tab to specify the following settings:
- Delete Server Stats After - The number of months that the server stats will
be deleted. By default, the server stats are deleted after 13 months.
- Enabled - Select this checkbox to delete server stats after the specified
time period.
- Delete Domain Stats After - The number of months that the domain stats will
be deleted. By default, the domain stats are deleted after 13 months.
- Enabled - Select this checkbox to delete domain stats after the specified
time period.
- Delete User Stats After - The number of months that the user stats will be
deleted. By default, the user stats are deleted after 13 months.
- Enabled - Select this checkbox to delete user stats after the specified time
period.
Indexing
Use this tab to specify the following settings:
- Max Threads - The maximum number of threads to use for search indexing. Increasing
this value will cause SmarterMail to use more CPU, but will allow the system to
index more users simultaneously.
- Segment Count Before Optimizing - The number of segment counts in an index
before the index is reorganized. Increasing this number will increase file counts
per mailbox, but will use less CPU.
- Items Before Garbage Collection - The number of indexed items across the
server before freeing as much memory as possible. Increasing this number will increase
memory usage and lower CPU usage.
- Items to Index Per Pass - The number of items to index per user per index
attempt. Increasing this number will increase memory usage and decrease the time
it takes to index one user. However, it will increase the length of time it takes
to index many small users if there are a few large users.
- Seconds In Queue Before Indexing - The amount of time a user must be in the
indexing queue before being indexed. This setting provides a buffer for many changes
to a mailbox to ensure the same user is not indexed multiple times. Increasing this
number will cause search results to be delayed further, but will result in indexing
heavier users less frequently.
- Deleted Items Before Indexing - The number of items that will be removed
from the index before an optimization will occur. Increasing this number will slow
search results. Decreasing this number will increase CPU and disk usage, but will
increase search result speed.
