Exchange smtp queues stay active even though all emails from queue have been sent
Posted on 2007-12-06
I have Windows SBS2003, we send out an email to our customer base occasionally. These are small emails (under 0.5 MB) however due to our distance for the local bt exchange we can only get a 1MB ADSL connection. The email is sent in the evening to around 800 people, this generates about 500 queues in MS Exchange. Once the queue is empty [0 messages] it stay sactive. This obvoiusly compounds are very limited bandwidth still further.
Why does an empty queue stay active? How can I resolve this? I have 193 active but empty queues, this is fairly typical the morning after sending an email to our customer base.
(I do sometimes use a batch file based on aqadmil.exe to delete any remaining emails sent but no yet delivered [in Retry] to reduce the backlog of emails queueing, this again will leave me with empty but active queues.)
