Outgoing Mail Limit has changed.

Outgoing Mail Limit has changed.

Recently we started getting blocked for outgoing mail exceeding the limit.
This was odd because it has been fine for a long time.

Finally I checked the email policy and saw that the greyed out range was 1 - 50
However in our box it read 100.
This would be fine.

Playing with other settings I noticed you could not enter numbers exceeding the range. This then implied we used to have a limit of 100 and since it has been reduced to 50.

As we send email via our website using SMTP a higher limit is important to reach the membership.
Is there a higher limit available to paid accounts? or a way to fix this?
