-In the change from version 5.7.3p2 to 5.9.2p1 the ownership and permissions
-changed for the /var/spool/offline directory
+Alpine hangs when sending mail using the opensmtp sendmail command and the
+opensmtpd server is down.
+
+To prevent this, modify the /etc/pine.conf or the user .pinerc to
+send the mail directly to the server instead of using the
+opensmtpd sendmail command:
+
+  smtp-server=localhost
