Problemsendmail must be compiled with SASL support before it can be configured to offer the AUTH protocol extension. SolutionCheck the sendmail compiler options. If sendmail was compiled with the SASL flag, it does not need to be recompiled. If sendmail was not compiled with SASL support, add SASL to the -D flags used to specify compiler environment information, add sasl to the -l flags used to select libraries for linking, and recompile sendmail. After recompiling sendmail, reinstall and restart it. DiscussionUse the -d0.1 flag to check the compiler options of the sendmail binary. The SASL flag should be clearly shown in the "Complied with:" list, as in this example: # sendmail -bt -d0.1 Version 8.12.9 Compiled with: DNSMAP LOG MAP_REGEX MATCHGECOS MIME7TO8 MIME8TO7 NAMED_BIND NETINET NETUNIX NEWDB PIPELINING SASL SCANF USERDB XDEBUG ============ SYSTEM IDENTITY (after readcf) ============ (short domain name) $w = chef (canonical domain name) $j = chef.wrotethebook.com (subdomain name) $m = wrotethebook.com (node name) $k = chef ======================================================== ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address> > /quit If the flag is not displayed, create a site.config.m4 file in the devtools/Site directory that contains the following commands: APPENDDEF(`conf_sendmail_ENVDEF', `-DSASL') APPENDDEF(`conf_sendmail_LIBS', `-lsasl') Recompile, reinstall, and restart sendmail, as in this example: # cd /usr/local/src/sendmail-8.12.9 # ./Build -c ...many lines of output deleted... # cd /usr/local/src/sendmail-8.12.9/sendmail # ./Build install ...many lines of output deleted... # kill -HUP `head -1 /var/run/sendmail.pid` See AlsoRecipe 1.2, Recipe 1.3, Recipe 1.4, Recipe 1.6, and Recipe 1.7 provide additional examples of compiling sendmail. Chapter 7 covers SASL and AUTH configuration. The sendmail book covers AUTH configuration in Section 10.9 and compiling sendmail in Section 2.2. See the sysadmin.html file in the SASL documentation directory for additional information about SASL configuration. |
