Message Rejected - Size Limit
BarWeb along with all other email providers have an email size limit, if you are attempting to send an email and it is rejected with a message about Size Limit, this is usually caused by a large attachment on the email.
BarWeb has a limit of 150MB for both Standard and Exchange accounts, our inbound email size limit from external servers (Office365, Gmail, etc...) is also 150MB.
To stop a message being rejected with a Size Limit message please ensure that the message you are attempting to send, or trying to receive is under 150MB.
