Question

I tried exim4 start, but now I get this error: lookup type "mysql" is not available. I installed exim4 with apt-get install exim4. How can I fix this?

mysql必须进行编译才能作为查找类型使用。您可以通过运行exim4-bV（或exim，或sendmail，或exim二进制文件的实际名称）来查看可用的查找。以下是我的一个服务器的输出示例（请注意，我没有在其中编译mysql）：

g3 0 /home/jj33 > exim -bV | grep ^Lookup
Lookups: lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmnz dnsdb dsearch passwd

我似乎记得Debian（因此可能还有Ubuntu）有一个类似于exim4heavy的包，它是exim，里面编译了所有的铃铛和口哨。你可以看看。我似乎还记得，一些包商为查找类型维护了自己的私有动态加载程序，因此在Debian/Ubuuntu中，您可能会加载exim4-mysql包或类似的包，并提供查找。
