Errors and Common Configuration Parameters
Examples and Help
queue file size limit exceeded
The topic is mailbox size limit and message size limit .
By default, Postfix limits the size of an email, restricting the recipient from receiving any email size greater than the default limit. The sender of the email will receive a bounced email with an error.
Remote host said: 552 5.3.4 Error: message file too big
This default setting can be modified by adding the following line to the bottom of: /etc/postfix/main.cf
message_size_limit = 0
The zero indicates NO LIMIT. You may wish to set a limit that is reasonable.
Once you have added the above line and saved the file, you will then need to reload postfix.
postfix reload
A more reasonable example might be 20mb as a limit. Emails with attachments shall not exceed that size.
message_size_limit = 20480000
Also, you could set it to 50mb
message_size_limit = 52428800
There is also a setting for mailbox size limit.
mailbox_size_limit = 51200000
It could also be your virtual_mailbox_limit if you are piping your email to another process.
virtual_mailbox_limit = 0
Error: Postfix - virtual_mailbox_limit is smaller than message_size_limit
Increase the value of virtual_mailbox_limit. By default, it's set to 51200000 bytes.
virtual_mailbox_limit = ${message_size_limit}0
You can enforce a factor of 10 difference, provided the message size limit is not larger than 200MB.
