    I need some help, this is killing me!! It was working fine and just decided to stop sending mail after a reboot one day.

    If I telnet to my server on port 587 I get

    250-size 10240000
    250-auth plain login
    250-auth=plain login
    250 8bitmime

    If I try and send mail through outlook on port 587 a username and password dialogue box comes up and it won't accept the authentication, even though I know it is right. Receiving mail is fine, and I can send to other domains I host.

    Can anyone help please??

    Any more info needed??
