I am new to this so please excuse a silly question. I was told that Plesk allows me to adjust the size of the email that can be sent but I can't see anywhere in the Mail control panel that option. There is a mailbox size which is unlimited as default (fine by me). Is there a default email size that Plesk sends? I want to be able to send big emails, 20Mb and I need to make sure Plesk will let me do that. If it's possible, where do I adjust that? Please can anyone help? I sent a test message to someone with 12Mb message and got the following error back (Message size exceeds fixed maximium message size). Thanks!
