It will help.
bimmer,
You can turn off relaying without affecting its mailing capability unless you use IMAP and POP connections. You can however go in to configuration connections then internet mail service and the routing and under the routing restrictions options set the internal address range and clients who authenticate as an option. This will stop non authenticated relaying.

Toker ... i have no idea man ... we don't have a web site ...
and whats going on as follows.
u might recieve a mail from my company ...
for example : the sender is : [email protected] ... but actually we don't have this address in our company ....
and as for DJM : if u mean the unix based send mail .. then, NO .. they use Exchange ( Intel Based Server ).
ok guys ... WHAT !
my client start shitting on me ...
i think the software firewall solution seems a good one ... does the ISA server work for that ( Proxy server ) ... ?
Also check out this site:
http://mail-abuse.org/tsi/ar-fix.html
It has pointers for fixing relaying problems on most of the popular 'mailer' programs.
DjM
Including Exchange.
Bimmer, listen to what Paul & I had to say. This will fix 90% of your problem without a firewall, though you should have some sort of firewall to protect your network, on a different computer from your email server.
I've don that ... it stoped the out going spam for a while ... but then everything got back ?Quote:

weird ... isn't it !!
Bimmer, I pointed you to the solution. There is a fix for Exchange 5.5.
Check this: http://www.exchangeadmin.com/Article...ArticleID=7696
and this: http://www.microsoft.com/technet/tre...l/excrelay.asp
Follow the instructions and turn off relaying.

a firewall wont help as port 25 needs to be open anyway to recieve your mail
Bimmer,
You need to stop and start the Exchange internet mail service for it to take effect if you have not already done so
