Mysteriously I am no longer able to send large email messages, because I get an NDR saying "This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again."
This is the same as described in a past questions that was resolved by a restart of the Server but this did not resolve my problem.
I have no restrictions set in any of the following places:
Global Settings > Message Delivery > Properties> Defaults
Protocols >Default SMTP Virtual Server > Properties > Messages
Connectors > Default SMTP Connector
Active Directory Users and Computers> User Properties
What is realy wierd is that this is a problem that has cropped up, when previously it was OK.
Can anyone suggest what the problem may be
