New Features and Bug Fixes in beta 13th February 2008

1 - DUN Manager no longer gives an exception when being closed down if one or more of the time servers was unable to start due to an existing time server already running on the same PC.

2 - When using the Set PC Clock scheduled task, if the time error is more than two seconds, the setting is no longer ignored if the round trip time is more than two seconds, or if the discrepancy between two NTP servers is more than two seconds. These changes will allow the time to be corrected if a rogue NTP server is specified, that's always very slow.

3 - In the View Task Log window, a new column Char/sec has been added which shows FTP download or upload performance in characters per second. This column and File Size both now show shortened numeric values, ie 3.3M instead of 3,300,000.

4 - The Scheduled FTP Download and Upload tasks support some new FTP commands for improved performance, including: One Time Passwords (S/key) which automatically encrypts the logon password if requested by the server, ALLO to check if sufficient disk space for an upload, XMD5 to check for corruption, and SITE DMLSD for faster recursive directory listings. The FTP General tab has new tick boxes that disable certain FTP features if these cause problems. 'No Extra Features' stops the FEAT and ALLO commands being sent if the server does not respond correctly to any of the various advanced commands. 'No Mode Z Compress' stops uploads and downloads being compressed for speed, perhaps on fast networks which are sufficiently fast already. 'No TMP File for Up/Download' means that files are transferred with their original names, instead of the temporary name normally used to avoid partial files being left if transfer is interrupted, but sometimes the final rename to the correct name fails.
'No MD5 or CRC Check' disables the integrity check after a transfer, which can take a long time on very large files. On the FTP Common tab, the 'Interface IP Address' may now be selected from a drop down box, if the PC has more than one IP address and the FTP server expects to see a specific address. There are various FTP fixes relating to resuming failed file transfers.

5 - In the Telnet window, if a log of the session is specified, it is now correctly started and stopped, and a separate log for each session written to the specified logging directory with a file name format telnet-yyyymmdd-hhnnss.

6 - The Check for Mail and Relay Mail scheduled tasks now support SSL/TLS for POP3 and SMTP mail servers, such as Goggle Mail. There is a new drop down box next the server port for both POP3 and SMTP mail, that defaults to 'Not Secured'. Changing the box to 'SSL/TLS connection' will also change Port to 995 for POP3 and 465 for SMTP and will cause DUN Manager to start an implicit TLS connection to this port, which will be refused is SSL/TLS is not available. Google Mail uses 'SSL/TLS connection' for pop.gmail.com and smtp.gmail.com. Changing the box to 'SSL/TLS Authentication' will default the port to 110 or 25 and will cause DUN Manager to start a normal POP3 or SMTP session, but it will check if the server returns a STARTTLS response to indicate it supports SSL/TLS at which point a secure connection is established instead, or the server is closed. SSL/TLS has been tested with Google Mail, CIX and Merula. Goggle supports 'SSL/TLS connection' for pop.gmail.com (port 995) and smtp.gmail.com (ports 465 or 587). Merula supports 'SSL/TLS Authentication' for POP3 on galahad.merula.net and SMTP on post.merula.net. CIX supports 'SSL/TLS Authentication' for POP3 on
mail.cix.co.uk. Note that Goggle Mail needs POP3 mail to be activated through the account control panel, and requires 'recent:' to be added before the account name in order to read all items in the mailbox. Note that DUN Manager does not currently attempt to verify the server's SSL certificate.

7 - For compatibility with MailMaint Release 3.5 and later, the POP3 Mail Server tab allows the names of up to three extra custom header fields to be specified to be stored and displayed (in MailMaint). There is a new mini grid in which three header names may be specified, ie 'X-Spam-Level:', which are case insensitive but must have the trailing colon, then the column title that should appear in MailMaint. Note these settings should be the same as those in MailMaint. The new header names may be used in the Spam Detection Filters.

8 - If Windows Explorer crashes and the task bar is rebuilt, the DUN Manager system tray icons will now automatically re-appear.

9 - Fixed a bug where the pop-up notification window may have clipped some text with certain Windows desktop styles.
