Technically you could use FTP server as attachment directory, but SquirrelMail might be unable handle additional FTP errors. Document about sessions in database was created because people can use database to store session data, not because it is useful in some real setup. Person that wrote initial doc tested it on local setup. Such setup is deviation from standard PHP settings and it might trigger some issues that are not visible in standard file based session handler. -- Tomas -- View this message in context: http://www.nabble.com/Question-about-data_dir-and-attachment_dir-when-using-MySQL-backend-with-squirrelmail-tp21175274p21192737.html Sent from the squirrelmail-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
