Hello Todd, Thanks for the reply. I have also got another suggestion from Mr.Odhiambo. I just applied it and it seems working now. I am monitoring to make sure not one are abusing our SMTP
Her's the suggestion from Mr.Odhiambo Look for this in your Exim configuration file: > # Accept if the message arrived over an authenticated connection, from > # any host. Again, these messages are usually from MUAs, so recipient > # verification is omitted. > accept authenticated = * > Change it to read: > accept authenticated = a.b.c.d > You get it? > -- > Best regards, > Odhiambo WASHINGTON, > Nairobi,KE > +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Aneesh Joseph | System Administrator | T: +919895012331 | [email protected] |http://www.hellosystemadmin.com Chat [image: Google Talk:] aneeshjoseph [image: Skype:] aneeshjoseph [image: Linkedin] <http://www.linkedin.com/in/aneeshjoseph>[image: Facebook]<http://www.facebook.com/profile.php?id=595728820>[image: Orkut] <http://www.orkut.co.in/Main#Profile?rl=fpp&uid=3496974728077767766>[image: Twitter] <http://twitter.com/hellosysadmn> On Thu, Sep 22, 2011 at 11:06 PM, Todd Lyons <[email protected]> wrote: > Honestly the easiest option to me is to put an iptables rule on the > mail server which rejects port 587 (you do require smtp auth to run > only on port 587, right?) except for 1 IP, that of the webmail server > you wish to allow. > > ...Todd > > On Wed, Sep 21, 2011 at 9:39 PM, Aneesh Joseph <[email protected]> > wrote: > > Hello, > > > > I have a mail server and a web server.
