mail queue is full can we redirect the mail through another service
Posted on 2009-04-28
Excuse my limited Exchange knowledge, i know enough to be incredibly dangerous.
We have a number of servers running Exchange quite successfully and have very few problems. Recently though we've noticed more and more that mail queues are getting backed up due to either a problem with the ISP, spam issues etc..
As a result sometimes it can be several hours before it's realised that mail is being delayed or not being sent out at all.
i was wondering if there is a way that if mail is not going out i.e. via a smart host or via the ISP's SMTP server then can there be a secondary SMTP/smarthost to send the mail through.
We do have an event monitoring service going in on all of these servers which will advise us that the mail queue is filling up, but it wont automate the process of actually trying a secondary mail host to get the mail out for us.
Appreciate thoughts, ideas and best practices.
