The actual Rocky Linux has the same problems with the Exim 4.99 buildchange, than Fedora had. Yes, Fedoras builds are fixed. The issue with Rocky is, i can’t give you the exact path you have to look for the mysql/postgre lookup libraries. But, you can use the same workaround for this issue as we did in Fedora.
You find it here:
As of this time now, the Fedora Maintainer did not react to the bugreport or started a new build, so you get the quick & dirty fix from me now:
All Exim 4.99-1 builds for all architectures have the same mysql backend bug: it does not work anymore.
This is caused by a configure mistake the maintainer has done before compiling the source code. As a result, the refered to mysql-lookuplibraryname is wrong:
traditionally, Fedora Exim used this name schema: „/usr/lib64/exim/<version>/lookups/mysql.so“, but the Exim 4.99-1 build referes to :
openat(AT_FDCWD, "/usr/lib64/exim/4.99-1.fc42/lookups/mysql_lookup.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
failing to find, what is not existing there.
The quick workaround is to symlink the used name to the real lib name:
cd /usr/lib64/exim/4.99-1.fc42/lookups ln -s mysql.so mysql_lookup.so
You do not even need to restart Exim, because this is not a runtime issue.
