Hi, i use openemm for send weekly newsletter to our customers. Openemm use sendmail for send email.
My problem is that send is very slow, for service sendmail status only return 2 process.
For send 50k emails take 24 hours.
I attach the config of
server has 4 gb ram

    50k emails is a lot for one server. What is the size of each email? How much bandwidth is available for this server?

    Some sites will do throttling on you since you're sending so much mail. Like yahoo might tempfail you because you sent to too many of their users, so it'll take that much longer to deliver them all.

    Author Comment

    Bandwidth: 50 mbps
    The problem is that sent many slow, this systems should send 50k in 2-3 hours.
    So, i read that can be configurable the limit of emails per hour to ip, and config the sends to yahoo, hotmail, etc.
    Can you check my config file?
