I just got the same problem. I'm using a separate sendmail.cf Updating from sendmail-8.11.0-8 to sendmail-8.11.6-1.7.0 on i386 gives the following errors in the maillog: Sep 11 10:04:46 mail sendmail[11088]: f8BA4kD11088: tcpwrappers (ch5as09-73-244- 208.cw-visp.com, 212.137.244. 208) rejection Sep 11 10:04:46 mail sendmail[11088]: NOQUEUE: ch5as09-73-244-208.cw-visp.com [212.137.244.208] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0 Sep 11 10:07:04 mail sendmail[11094]: f8BA73D11094: tcpwrappers (ex3lujmoims01.cec.eu.int, 158.169.9.54) reje ction Sep 11 10:07:04 mail sendmail[11094]: NOQUEUE: ex3lujmoims01.cec.eu.int [158.169.9.54] did not issue MAIL/EXP N/VRFY/ETRN during connection to Daemon0 Sep 11 10:12:57 mail sendmail[11160]: f8BACpD11160: tcpwrappers (corp1.cbn.net.id, 202.158.3.24) rejection Sep 11 10:13:08 mail sendmail[11160]: NOQUEUE: corp1.cbn.net.id [202.158.3.24] did not issue MAIL/EXPN/VRFY/E TRN during connection to Daemon0
I'm having the same problem. Sendmail worked fine till the RPM. Now what????? Does Red Hat provide FREE support for what they break?
FIX: vi /etc/hosts.allow Sendmail: ALL ChangeLog mentions this vaguely: * Fri Mar 2 2001 Nalin Dahyabhai <nalin> - tcp-wrapper support wasn't enabled correctly #21642 * Fri May 19 2000 Florian La Roche <Florian.LaRoche> - enable tcp_wrapper support This should have been clearly documented in the update notice...
I can't get the /etc/hosts.allow fix to work. I even put in an "ALL : ALL" temporarily as a test, and still the connection was refused by sendmail. Any other ideas? Come on Red Hat. Where's the fix? You really botched this one, taking out all of our mail servers like this.
This was sent to me via Red Hat so I copied and pasted the fix. Hope that isn't a problem JE Ok, most of us have probably seen this, and if you haven't you can have it to look forward too. Customers will upgrade sendmail because of the errata and alot of folks will now have a broken sendmail. Here is what is going on: IF they have never changed their /etc/sendmail.cf file and do the upgrade, that file will be updated to the "stock" sendmail.cf. This stock version DOES NOT allow any incomming connections. This is just like we have delt with since Red Hat Linux 7.1 was released. So even if they have Red Hat 6.1 and upgrade, they now have the same issues to deal with that 7.1 had. So how do you fix it..... find this line in /etc/mail/sendmail.mc DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA') and put dnl in front of it. dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA') save the file and issue this command: m4 /etc/mail/sendmail.mc > /etc/sendmail.cf then issue service sendmail restart If incomming mail still does not work, then you need to check one other place. This new version of sendmail has tcpwrappers compiled in. So even though someone using tcp wrappers before never had a problem with sendmail, if they upgrade and havent accounted for it, it will break sendmail and it will not work. what do you do...... check /etc/hosts.deny If there is anything in it, that does not start with "#", especially if it has a line in it like this: All: ALL Sendmail will not work. They will have to add an entry to /etc/hosts.allow to permit outside connections to sendmail. I haven't tested this but this "should" work: /etc/hosts.allow sendmail: ALL This should fix any problems you run across, that are caused from the upgrade.
One thing I had to do that is different to restart sendmail is: /etc/rc.d/init.d/sendmail restart
There is a updated rpm available via ftp/Red Hat Network that should fix the problem that the default configuration only enabled network access for localhost instead of for all network devices. Thanks, Florian La Roche
