Email Quota Limits

Postby Gfw » Mon Apr 11, 2016 11:06 am

I am running version 9.11. There appears to be a 1,000 message per hour quota which I need to increase. I found the following...

451 Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later.

Post Office Restriction - Administration->Post Office configuration->Restrictions->Limit Maximum SMTP recipients

Mailbox Restriction - Administration->Post Office actions->Create Mailbox->Restrictions->Limit SMTP usage to a maximum of

I can't seem to find the Administration link. What am I missing? :?:

"Administration" is referring to the MailEnable administration console. You need to navigate within the console to: Messaging Manager > Post Offices > (postoffice name). Right click on the postoffice and select properties. Next navigate to the "Restrictions" tab.
