scusa me lo ripeti in soldoni?

forse devo configurare sendmail, dato che quando lo avvio mi da questo errore:

Starting sendmail MTA daemon: /usr/sbin/sendmail -L sm-mta -bd -q25m
/usr/sbin/sendmail: error while loading shared libraries: libsasl2.so.2: cannot open shared object file: No such file or directory
Starting sendmail MSP queue runner: /usr/sbin/sendmail -L sm-msp-queue -Ac -q25m
/usr/sbin/sendmail: error while loading shared libraries: libsasl2.so.2: cannot open shared object file: No such file or directory


devo installare la libreria giusto?
