How many messages can the software send per hour?
We often receive questions about the speed of the
program. The answer is: it depends.
Not MailList Controller
defines the speed, its the environment. The message
speed depends on the internet connection (upload
speed), the connection to your mailserver, the
mailservers performance and the size of the message.
- a DSL connection has a speed of 2048/256 kbit/s
this means the upload speed is 256 kbit/s, which
equals 256 kbit/s /8 = 32 kbyts/s
if the message has a size of 32 kbyte, then you can
send (theoretically) 1 message with a size of 32
kbyte per second
- Upload speed: 512 kbit/s = 64 kbyts/s
- Upload speed: 1024 kbit/s = 124 kbyte/s
If you have a mailserver in your local network, then
the speed is very high. You could send out a large
number of messages within a short time. In some cases it
could be required to slow down or limit the speed.
MaillList Controller has such options to define a
slowdown or limit the max. number of messages per hour.
Hint: Some anti-virus programs, which have an option
to "scan outgoing messages" have problems with
a larger number of messages and can slow down the send
Please note, that the program cannot send out more
messages as your mailserver allows. Some mailserver have
limits, e.g. some allow to send only x messages per
hour. Please use the List Settings -> Outgoing
Messages (SMTP) -> Limit feature to adjust the
program to any limit.
Mailserver Pickup Directory:
This option can be used if you are running a local
mailserver, which has a pickup directory. In this mode,
the program does not send using SMTP. It creates a .eml
file in the pickup directory for each message, which
will be used directly by your mailserver. The mailserver
picks up the .eml file and sends it.
MailList Controller will create the messages in the
pickup directory very fast: up to 100.000 messages in
less than 5 minutes, so it might be required to slow
down or limit the number of messages per hour, if your
server runs out of resources.
This option is the fastest way to send out messages if
you are running a local mailserver, which has a pickup
directory. Please note, that the program does not
receive any confirmation from your mailserver and your
mailserver is responsible for sending out the messages
an error processing. Please refer to the user manual of
your mailserver for further details.
