src/login-common/ssl-proxy-openssl.c:763: undefined reference to `SSL_CTX_set_info_callback'

If you get the following error when compiling dovecot:

src/login-common/ssl-proxy-openssl.c:763: undefined reference to `SSL_CTX_set_info_callback'

Then edit that file, eg:

cd /usr/local/directadmin/custombuild/dovecot-1.1.2
nano src/login-common/ssl-proxy-openssl.c

Go down to line 762/763 and find this code

    if (verbose_ssl)
        SSL_CTX_set_info_callback(ssl_ctx, ssl_info_callback);
        

and replace it with:

//    if (verbose_ssl)
//        SSL_CTX_set_info_callback(ssl_ctx, ssl_info_callback);

to uncomment it. Then type:

make
make install
