Exchange, SMTP connectors, Email Attachment Sizes
Posted on 2009-02-17
I am the admin for a small network running MS Server 2003 and exchange 2003 with about 130 users and email addresses. Some of the sent emails are starting to come back with delay NDR and then after about 20-30 delivery failures, the mail finally times out.. I have noticed that it is only email with attachments over 3mb... I have done everything I can to up the attachment sizes including:-
a. System Manager/Global Settings/Message Delivery/Defaults and then all including (Sending message size, Recieving Message size, Recipients Limits are all set at 20000kb
b. All users Mailboxes are within Limits and have been checked one by one to make sure that the Delivery Restrictions within the user properties and set to use default limits..
Is there anything else that needs to be done to increase the size that emails can be sent.
Any help would be greatly appriciated..
