Hi postfix friends,
usually I've always found a solution when I ran into postfix problems. Even the change from postfix 2.11 on old 14.xx ubuntu distribution to the 20.04 LTS (forgot the postfix version) was not a big deal, everything ran smooth. But now, with a release-upgrade from 20.04 LTS to 22.04 LTS there has been a postfix update to 3.6.4 and now not a single (sub-)process of postfix starts and there's no log entry nor error message in mail.err, the process seems to die absolutely silently. I'm still using my old configuration files (sorry for that) because it has been a lot of work to get postfix/postgrey/amavisd and many more processes working together properly. In the "old world" everything starts up as expected: root@berilia:/etc/postfix# netstat -tulpn | grep master tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN 7429/master tcp 0 0 0.0.0.0:587 0.0.0.0:* LISTEN 7429/master tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN 7429/master tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 7429/master tcp6 0 0 :::587 :::* LISTEN 7429/master tcp6 0 0 :::465 :::* LISTEN 7429/master tcp6 0 0 :::25 :::* LISTEN 7429/master But now, in the 3.6.4 world there's no process for smtp: root@jerakeen:/var/log# netstat -tulpn | grep master root@jerakeen:/var/log# So I looked into the /var/log/mail.log and *.err, but there's no message except for this after reloading the config: Oct 1 22:04:42 jerakeen postfix/postfix-script[1901]: refreshing the Postfix mail system Oct 1 22:04:58 jerakeen postfix/postfix-script[1911]: refreshing the Postfix mail system Oct 1 22:08:04 jerakeen postfix/postfix-script[1927]: refreshing the Postfix mail system Oct 1 22:12:46 jerakeen postfix/postfix-script[2029]: refreshing the Postfix mail system Oct 1 22:22:35 jerakeen postfix/postfix-script[2058]: refreshing the Postfix mail system Postfix itself says it's running (but with remark "exited" in brackets). Then I thought: "Well, let's try what they said about debugging, catching all necessary information with strace (in my case)". But: After reload I can see ... nothing. It seems that postfix for some reason does not start any subprocesses (or how the "master" process should be called). On the other hand: There's no "postfix" process at all although the systemctl statement says that postfix ist active. In my old system I can see these processes: root@berilia:/etc/postfix# ps -ef | grep -i postfix root 7429 1 0 Sep21 ? 00:00:38 /usr/lib/postfix/master postfix 7437 7429 0 Sep21 ? 00:00:04 qmgr -l -t fifo -u postfix 7438 7429 0 Sep21 ? 00:00:03 tlsmgr -l -t unix -u postfix 24361 7429 0 21:16 ? 00:00:00 pickup -l -t fifo -u postfix 24563 7429 0 22:35 ? 00:00:00 smtpd -n smtp -t inet -u -o stress= -s 2 postfix 24565 7429 0 22:35 ? 00:00:00 anvil -l -t unix -u root 24580 23931 0 22:39 pts/1 00:00:00 grep --color=auto -i postfix On my new system which has worked fine until upgrading it to 3.6.4 I can see no single postfix entry: root@jerakeen:/var/log# ps -ef | grep -i postfix root 2136 1514 0 22:41 pts/1 00:00:00 grep --color=auto -i postfix Do you have an idea how to proceed? I now see that postfix does not start at all, but without any trace when reloading config, I can't see a chance to get information why postfix does not start anymore. Right now I'm working on a virtual machine (VirtualBox, latest version), but this worked fine with ubuntu 20.04 LTS and the corresponding postfix version. Yesterday I did a do-release-upgrade and everything works fine right now, even Apache2/PHP/phpmyadmin/roundcube ... but postfix is on strike some- how. ----------------------------------------------------------------------------------------------------- Act II: Postfix does not start at all as I saw right now. And the stopping also gives strange messages: root@jerakeen:~# postfix stop postfix/postfix-script: stopping the Postfix mail system Oct 02 16:24:11 derdickehase postfix/postfix-script[3222]: stopping the Postfix mail system /usr/libexec/postfix/postfix-script: 216: kill: No such process /usr/libexec/postfix/master: symbol lookup error: /usr/libexec/postfix/master: undefined symbol: var_compat_level postfix/postfix-script: waiting for the Postfix mail system to terminate Oct 02 16:24:11 derdickehase postfix/postfix-script[3225]: waiting for the Postfix mail system to terminate /usr/libexec/postfix/master: symbol lookup error: /usr/libexec/postfix/master: undefined symbol: var_compat_level postfix/postfix-script: waiting for the Postfix mail system to terminate Oct 02 16:24:12 derdickehase postfix/postfix-script[3228]: waiting for the Postfix mail system to terminate /usr/libexec/postfix/master: symbol lookup error: /usr/libexec/postfix/master: undefined symbol: var_compat_level postfix/postfix-script: waiting for the Postfix mail system to terminate Oct 02 16:24:13 derdickehase postfix/postfix-script[3231]: waiting for the Postfix mail system to terminate /usr/libexec/postfix/master: symbol lookup error: /usr/libexec/postfix/master: undefined symbol: var_compat_level postfix/postfix-script: waiting for the Postfix mail system to terminate Oct 02 16:24:14 derdickehase postfix/postfix-script[3234]: waiting for the Postfix mail system to terminate /usr/libexec/postfix/master: symbol lookup error: /usr/libexec/postfix/master: undefined symbol: var_compat_level postfix/postfix-script: waiting for the Postfix mail system to terminate Oct 02 16:24:15 derdickehase postfix/postfix-script[3237]: waiting for the Postfix mail system to terminate postfix/postfix-script: warning: stopping the Postfix mail system with force Oct 02 16:24:16 derdickehase postfix/postfix-script[3239]: warning: stopping the Postfix mail system with force What can I do? Installing Postfix from source in an older or in a newer version? ------------------------------------------------------------------------------------------------------------------- Act III Today I tried to install postfix 3.7.2 manually. I was enable to include MySQL support as well as TLS support. But the SASL (sasl2 / cyrus) configuration as given by page https://www.postfix.org/SASL_README.html does not work at all. When trying to send mails the answer of postfix (logging to stdoud) says: postfix/smtpd[10184]: warning: smtpd_sasl_auth_enable is true, but SASL support is not compiled in And this seems to be right, postfix and ldd say the same: root@jerakeen:/stage/postfix-3.7.2# postconf -a root@jerakeen:/stage/postfix-3.7.2# postconf -A root@jerakeen:/stage/postfix-3.7.2# ldd /usr/sbin/postfix | grep sasl My ideas are reaching the end for today, I've no clue why making postfix with SASL does not work on my ubuntu 22.04 LTS server. This is my make command I used in the end: make tidy && time make CCARGS="-DUSE_TLS -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DHAS_PRCE -I/usr/include/prce2 -DHAS_MYSQL -I/usr/include/mysql" AUXLIBS="-lssl -lcrypto -lmysqlclient -lz -lm -R/usr/lib/x86_64-linux-gnu -lsasl2" For me it's not that important to have a working 3.6.4 or 3.7.2 version of postfix but it would be great to get one of them to work properly. Does anybody encounter similar problems (either the first one or the second)? Best Regards, Martin -- _______________________________________________ [born at 328 ppm atmospherical CO2]
