We are having few problems with external emails being sent from lotus notes
being rejected by our exchange 5.5 server. Whenever an external user from
lotus notes sends an email to our network users where we use exchange 5.5,
the emails are rejected and the external users from lotus notes gets a reply
back saying that the destination users mailbox is full, but the users
mailbox is not full. Is there any known issues with exchange 5.5 and lotus
notes.
