spam relay
All, I think this is more freebsd related than just sendmail, but please forgive if I'm wrong, I have a server with virtual hosts using freebsd 4.0 and sendmail 8.9.3 and find the server domain user mail flooded with messages , definitely spam messages, that appear to be relayed by "[EMAIL PROTECTED]" I put "[EMAIL PROTECTED] 550" in /etc/mail/access and did makemap, and this stops the emails. I'm not comfortable doing this even though it works because as you can see, I have a general idea what I want to do but, really dont know proper way to handle this. any advise would be great! thanks Jan Jan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
Re: spam relay
www.sendmail.org could be a good starting point if you're using sendmail. I can't be more specific than that right now because I don't know what your target mail scheme is and I don't know if you want to stay with sendmail or try another mta such as exim or postfix. You might also want to look at ports/mail/rblcheck or somethign similar to help control who your server listens to. -- Ben W.

Re: spam relay
i had a similar problem with my open relay (setup for the convenience of my own users) back in college. here was what i did: * FEATURE(access_db, hash -o /etc/mail/access) * FEATURE(rbl) I'm sure it's pretty outdated, so I went to sendmail.org and found: anti-relaying page: http://www.sendmail.org/tips/relaying.html anti-spam cfg control: http://www.sendmail.org/m4/anti_spam.html hope this helps! /ayn On 0, Jan Voelker <[EMAIL PROTECTED]> wrote: > All, > > I think this is more freebsd related than just sendmail, but please forgive > if I'm wrong, > > I have a server with virtual hosts using freebsd 4.0 and sendmail 8.9.3 > > and find the server domain user mail flooded with messages , definitely > spam messages, > > that appear to be relayed by "[EMAIL PROTECTED]" > > I put "[EMAIL PROTECTED] 550" in /etc/mail/access and did makemap, > > and this stops the emails.

Re: spam relay
I'm not familiar with sendmail but It doesn't look like a freebsd issue to me. Make sure that you're not being used for relay and you should setup some black list rules. I use postfix and it's pretty easy to setup the rules once you understand how it works. This is the link to make sure that you're not being used by spammers http://members.iinet.net.au/~remmie/relay/ check out this link to see what you can do stop spam. http://imgate.meiway.com/index.cfm It talks about using it with Imail, but you can use it with anything. the program works great. I've been using it for couple of months and stopped over 3000 spam e-mails. - Original Message - From: "Ben Williams" <[EMAIL PROTECTED]> To: "Jan Voelker" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Wednesday, January 22, 2003 7:15 PM Subject: Re: spam relay > www.sendmail.org could be a good starting point if you're using > sendmail. > > I can't be more specific than that right now because I don't > know what your target mail scheme is and I don't know if you want to > stay with sendmail or try another mta such as exim or postfix. > > You might also want to look at ports/mail/rblcheck or somethign > similar to help control who your server listens to. > > -- > Ben W. > > Wednesday, January 22, 2003, 7:47:36 PM, you wrote: > > JV> All, > > JV> I think this is more freebsd related than just sendmail, but please forgive > JV> if I'm wrong, > > JV> I have a server with virtual hosts using freebsd 4.0 and sendmail 8.9.3 > > JV> and find the server domain user mail flooded with messages , definitely > JV> spam messages, > > JV> that appear to be relayed by "[EMAIL PROTECTED]" > > JV> I put "[EMAIL PROTECTED] 550" in /etc/mail/access and did makemap, > > JV> and this stops the emails.
