ip address switching

[stonedlizard]

Hello

we run sendmail at a client.
i have 2 users with problems of a total of 30.

they can send /recieve to accounts with the same suffix - something.co.za

they couldnt send to ANY external sites.

when i swopped their ip with a known good ip, it worked.
when i swopped it with a previously unallocated IP, it didnt.

any ideas?

Hi,
1) Check /etc/hosts.allow and hosts.deny
2) Check /etc/mail/access

Let me know if this helps. Im not a guru on this.
