    At the moment on our VPS the SMTP is reacting very slow.
    We are using the VPS for several scripts, like Newsletters and Webshops.
    SMTP sometimes isn't reacting at all, or very slow.

    Newsletter system gives errors like:
    - SMTP Error: Data not accepted.
    - The following From address failed:

    Also the PHP webshops are slow at the moment an e-mail is sent to the client or administrator. Also sometimes the shop software gives an error on when sending e-mail and does not send it at all.

    I tried restarting EXIM and IMAP but that did not help. Problems started about 4 days ago. Did run fine for months.

    Any suggestions here?
