I have a multi-installation server of ZCS, we are in phase of migrating from the old mail server to the new ZCS platform.
When testing migration with imapsync I got the error message of message is too big, I've modified message_size_limit to correspond to old server then I redid the test.
The number of errors diminished, but I still get
Code: Select all
msg Sent/115 {30023914} could not append ( Subject:[gdPanne], Date:["06-Nov-2018 10:10:06 +0100"], Size:[30023914] ) to folder Sent: Error sending 'APPEND Sent (\Seen) "06-Nov-2018 10:10:06 +0100" {30023914}': 418 BAD maximum message size exceeded
Code: Select all
zimbraFileUploadMaxSize 10485760
zimbraImapMaxRequestSize 10240
zimbraMailContentMaxSize 10240000
zimbraMtaMaxMessageSize 28311552
postconf message_size_limit 28311552
My question is how to configure these values?
Some articles make all of the equal, some others make the zimbraMailContentMaxSize double of the others.
Regards.
