This is still somewhat confusing. The e-mail gets to the sendmail queue on *WHICH* machine...the remote sender or the local reciever? Your description above makes it sound like your local mailserver cannot connect to the remote system which is trying to send mail, which doesn't make much sense to me. Please provide more details about exactly how you're trying to send mail, and any non-standard checks you're doing on your local mail-server (ie: ident check, SMTP verify to validate sender e-mail address, etc). Remember, all we know about your setup is what's in your e-mail... > The openings in the firewall for smtp are: > EXTERN_SMTP_PORTS = "0/0_ntp 0/0_smtp" This is very confusing. Looks like you're using one of my Dachstein releases, based on the kernel version, but the above configuration variable does not exist in the Dachstein firewall scripts. Even worse, I can't tell it was a simple typo, since you're mixing UDP and TCP protocols on the same line. If I'm reading between the lines properly, you need something like: EXTERN_UDP_PORTS="0/0_ntp" EXTERN_TCP_PORTS="0/0_smtp" Charles Steinkuehler http://lrp.steinkuehler.net http://c0wz.steinkuehler.net (lrp.c0wz.com mirror) ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
