Hi Victor, thank you for the reply, It looks like while both debian 10 and testing/14 have a dependency of the postfix package on libsasl2-2, in both cases libsasl2-2 merely recommends libsasl2-modules. Also, postfix merely suggests libsasl2-modules in both cases. However, for some reason on my debian 10 system, it shows libsasl2-modules having been installed automatically: % aptitude why libsasl2-modules i postfix Depends libsasl2-2 (>= 2.1.27+dfsg) i A libsasl2-2 Recommends libsasl2-modules (>= 2.1.27+dfsg-1+deb10u2) % aptitude search libsasl2-modules i A libsasl2-modules - Cyrus SASL - pluggable authentication modules I am curious that it shows installed automatically on my debian 10 system, as I don't understand why based on the dependencies. but on my testing/14 system, it had not been installed. After installing libsasl2-modules on the new system, the problem with relaying is fixed. CC'ing Michael Tokarev, the Debian package maintainer. IMO it seems like maybe postfix should require libsasl2-modules, the 300kB is well spent if you're installing postfix, rather than silently failing. But it might also make sense to update this text of SASL_README: | This same error message will also be logged when the libplain.so or | liblogin.so modules are not installed in the /usr/lib/sasl2 directory as that directory is not necessarily correct (for me it is /usr/lib/x86_64-linux-gnu/sasl2/), and it would be good to mention the package name for the most popular distros (libsasl2-modules), especially noting that the package may not be a postfix dependency and may need to be manually installed on some distros. thank you both, Greg _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
