Works very successfully for when our staff travel overseas and want to be able to send mail without having to change their settings. All good e-mail clients allow you to set an option that says "Check for new mail before sending mail". Even the crap ones...

I've progressed some of the sites on the ORBS list (in particular) and banning e-mail from them would be a major point for my disownment at work. The way my bosses look at is "We can hit the delete key, but if we haven't seen the mail in the first place, what can we do about it?"

Hello Frank, Sunday, April 08, 2001, 3:23:36 PM, you wrote: >> Is there an option for qmail? I only found some ugly >> patches/scripts/workarounds? FT> There are patches that do this. If they are ugly, I don't know. Ugly is the wrong word. I do not like to use patches and tools, this increases network documentation and costs a lot of time. At the moment of writing, i have learned a lot about qmail and its really interesting, but there are still things to solve for me. At the moment, qmail runs very well. Now i have to do some testings with smtp auth. I want to let in mails to rpcthosts and if the mail is not for these domains, an authorisation is required. I hope that this feature is possible. - dns-check: done with tcpserver - badmailfrom: done - smtp redirect: done - smtp auth: todo - virtual domains: todo - rbl/orbs: done with tcpserver/rblsmtpd... but i am not sure about the orbs patch, use or not to use -( -- Boris

This looks like a mixture of tcpserver's access rules and the badmailfrom control file of qmail. > Is there a qmail thingy to do the same? Yes - but more separated and cleaner. Relaying has nothing to do with spamming in the first place. Relay control and rejection of specified senders are different tasks and are provided by different programs in qmail. The relaying you control with the rules file of tcpserver, the bad senders are rejected by /var/qmail/control/badmailfrom. > Sometimes I think the qmail-people think that sendmail is an enemy to > qmail, but I can´t understand this. It's the difference in strategic design principles and of course coding practice that binds people to qmail and not sendmail. I don't trust sendmail but qmail. This is based on about ten years watching sendmails security problems. Regards, Frank

Hello Charles, thankyou for your answer, that will help me a lot.

Please explain how CC> this works with sendmail; then we can tell you if there's a qmail equivalent. Ok I will show you an example. I think its very important to understand both MTAs to decide what´s really better in what situation but this is another story. Here is an example of the access file. 192.168.0 RELAY 127.0.0.1 RELAY From:[EMAIL PROTECTED] 550 Spam denied From:[EMAIL PROTECTED] 550 SPAM F*CK YOU SH*T SPAMMER From:[EMAIL PROTECTED] 550 SPAMMER BUY YOURSELF From:[EMAIL PROTECTED] 550 LOAN YOURSELF, SPAMMER From:[EMAIL PROTECTED] 550 F*** YOU SPAMMER oo.net 550 SPMMMEE It looks like as if this file is similar as the rpcthosts (?) file on qmail, but its not the same. I relay incoming mails from my 192.168.0 class c network as well as localhost mails. But if there is coming a mail from "from:..." the mail will be rejected, and if there is a hostname only, the complete host is denied to send us any mails. This file has nothing to do with outgoing mails. I use this file to setup a mini-light spamfilter and to setup general relaying rules. Fetchmail delivers the mail to sendmail (at the moment to qmail, hahah) so the relaying is allowed. I think its very easy to setup and very easy to handle. Is there a qmail thingy to do the same? >> * Is there a way to forward all outgoing mails to a specific SMTP? CC> Yes, smtproutes. It's trivial. `man qmail-remote` for details.

CC> Charles There is a perl module somewhere I have seen on the qmail page I think I will try this first. Thanks for you answers, they helped me a lot. The next step is to find out how are virtual users working (users without system accounts). After that I think I have completed this part. Qmail is nice, but sendmail is not bad at all i was using sendmail a long time without any problems. Sometimes I think the qmail-people think that sendmail is an enemy to qmail, but I can´t understand this. -- Boris
