Q. What is the bandwidth used by imapsync?
|
|
|
|
R. From the host where imapsync runs, it opens two imap connections,
|
|
one with the source account at host1, one with the destination
|
|
account at host2.
|
|
|
|
So, the global bandwidth used is twice the volume of the source
|
|
account, one volume to download the messages from host1,
|
|
one volume to upload those messages to host2.
|
|
|
|
If the host2 is already filled with the messages, imapsync doesn't
|
|
transfer them and then the volume transferred is small, just the IMAP
|
|
commands to identify the messages on both sides.
|
|
|
|
There is no local cache of the email messages, except when a
|
|
message is very big, it is temporarly saved locally.
