Re: [qmailtoaster] check for mail from email address
hi thanks for the reply. i read thru the empf help files but not sure as to how i can use the same basically my problem is as such my customer's office pc got compromised and it was shooting out spam emails the spammer was authenticating using my customer's email id and password but his "from email id" was : anyth...@yahoo.com ... anyth...@hotmail.com and so on and sending to a variety of external email ids ... and since authentication was correct qmail was accepting emails. so what i need to do is to ensure that only if the from email id is u...@somedomain_on_my_server.com (domain part) should the email be accepted after smtp authentication now how should i accomplish this using empf if say my sample domain on my server is abc.com pqr.com how will i ensure that the "mail from email id" should be only u...@abc.com or u...@pqr.com who can send to any user on any server globally. thanks rajesh > Rajesh M wrote: >> hello >> i noted that as long as i smtp authenticate qmail does not check to ensure >> that the mailfrom email id (domain name part) exists in the rcpthosts file >> or not. >> i need to check to ensure that the domain part of the mailfrom email id is >> a domain hosted on my server. >> example if domain1.com is hosted on on my server and therefore present in >> rcpthosts file. >> and u...@domain1.com is sending an email after smtp authentication. then while accepting this email i would need qmail smtp to check to ensure >> that domain1.com is existing on the server. >> now the question is this possible by modifying the qmail smtp file and then recompiling the same ? >> secondly which parts should i need to modify, any tips on this would be helpful ? >> thirdly i would prefer not to modify the qmail smtp and would rather modify spamdyke if possible, any tips on this would be helpful ? thanks >> rajesh > > This is possible with the eMPF patch which is included with the Toaster.

[qmailtoaster] check for mail from email address
hello i noted that as long as i smtp authenticate qmail does not check to ensure that the mailfrom email id (domain name part) exists in the rcpthosts file or not. i need to check to ensure that the domain part of the mailfrom email id is a domain hosted on my server. example if domain1.com is hosted on on my server and therefore present in rcpthosts file. and u...@domain1.com is sending an email after smtp authentication. then while accepting this email i would need qmail smtp to check to ensure that domain1.com is existing on the server. now the question is this possible by modifying the qmail smtp file and then recompiling the same ? secondly which parts should i need to modify, any tips on this would be helpful ? thirdly i would prefer not to modify the qmail smtp and would rather modify spamdyke if possible, any tips on this would be helpful ? thanks rajesh - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.
