Hello all,
My server is currently just getting bombed with smtp connections.
What I would like to do is point all customers to another smtp server
but the down side is that alot of customers use port 587 to send mail.
But alot still use port 25. What is the best way to make an outbound
smtp server that will still allow my customers to auth on port 587. I
guess I could replicate the vpopmail database to the new smtp server
but then how would I make sure that end users that are emailing each
other that their emails will not get delivered to the smtp server?
You'll want to investigate the source of the connections before going
through all that work if you have not done so already.
I've seen instances where a virus/trojan/etc. on a single computer (or
two) could cause this.
To have 2 servers available for outbound you'd need to look at a shared
filesystem for delivery in the scenario you're outlining. If all the
connections are from the same IP/block you could add a rule in tcp.smtp
to allow relaying for the IPs needed on the new server as well.
