News

• Fixed an issue with attachments on the Web Interface.

• Optimized SMTP connections, and fixed a minor bug in IMAP connections.

• Fixed problems with POP3 connections;
• Fixed issues with using remote SQL server;

• Now DKIM checking for incoming messages honors signatures which are done "on behalf" of other domains;
• Fixed issues which would potentially cause high CPU usage in case of data corruption;

• Fixed problems with retrieving statistics to the UI;
• Fixed a problem with checking SPF records, containing IPv6 addresses;
• Added a feature to export server settings into Linux/Docker version, which is coming soon.

Preparing the release the version which will work on Linux. It required pretty significant changes.

This version requires .NET Framework 4.8 runtime/

• POP before SMTP and Trusted senders options are no longer available, because they are against modern security guidelines;
• Remoting interface has been removed. We will be replacing it with new RESTful API;
• Added support of TLS 1.3. Please note, that TLS 1.3 is not yet available on any Windows, but when it is out, it will work with the current version of the server;
• Multiple "behind of scenes" changes in the code to make the server more "responsive". Applies both to the service part and the User Interface

• Now problems, caused by AbuseIPDB being down are handled properly (further fixes);
• DKIM has moved out from the Anti-Spam box. Now any domain can be added to the list of domains, and if mail originates from them (FROM header), the server will append DKIM signatures;
• Ensured that the server will not generate duplicate Message-IDs. It was the case when messages coming in within very small intervals;
• Improved handling of 7-bit encoded messages. Message bodies were getting corrupted when retrieving through POP3;

• Now problems, caused by AbuseIPDB being down are handled properly;
• Fixed certain UI issues, when adding domains to the server;
• Fixed error handling, when setting up DKIM for mailbag and selector is not specified;
• Fixed Index out of Range error when received message contained empty body;
• Services Settings box are now more consistent with each other (no longer using Disable checkbox, replaced with Enable).

Now the server fully supports IPv6!

• Added IPv6 support to primary SMTP. Banned and trusted IP addresses now will accept IPv6 entries. DNSBL and SPF will work with IPv6 addresses;
• Now delivery can be performed using IPv6 connections;
• Fixed DKIM signature issues with simple/simple canonicalization method (the bug was introduced in 1.3.7.0, sorry);
• Improved error handling. Now, "More than one error has occurred" messages will be followed by a more detailed explanation, if available;
• Added IPv6 support to Recommendations;
• Added DKIM to Mailbag domains. In case a mailbag server is used to send mail out from mailbag domains, messages will be signed.

• If an incoming message contains multiple DKIM signatures from a domain, referred to in the FROM header, one with the "best result" will be taken into account;
• Now the server security can be tightened even more. Added two more options at Settings - Services dialog box:
  • SMTP - Common section, Accept mail ONLY if a connection is secure. If enabled, the DATA SMTP command will be accepted only if a connection is secure;
  • Delivery section, Deliver mail ONLY if a connection is secure. If enabled, and receiving mail exchanger does not support STARTTLS, or if a secure connection fails, mail will be bounced to sender;
  Note, that those options should be used with caution, only when security is a high priority. If they are used unnecessarily, some emails may be lost;
• Added DMARC to Recommendations (Tools - Recommendations), also the way of generating recommendations has been optimized.

• Added support of DMARC. See more about the implementation here.
• Removed checking of email addresses with sending servers, as outdated (Anti-Spam - Address Verification - Verify Addresses with Sender Domains). It still can be enabled. Check Mail Server FAQ or Contact us, if you want it back;
• Added a no-reply attribute to user accounts. If it is set, the server will reject all arriving mail to the account;
• Slightly improved log viewer.

• Fixed an issue with DKIM body hash calculations when messages contained lines starting with a single period;

• Added Calendar. It is served through web interface. See more here;
• Added SAVEDATE IMAP extension (rfc 8514);
• Improved Log Viewer (Logs - View Log). Now lines can be filtered. It makes it easier to folow single connection. Also, IP addresses can be highlighted in the log and sent straight to Banned Hosts, Trusted Hosts or Auto Lockout databases;
• Fixed an issue with Distribution Lists. They were case sensitive, and certain features were not working properly, if catch-all account was specified.
• AbuseIPDb Blacklists Database update now happens with low priority thread, and it should affect the server performance less during the database update;
• Server now includes console application ConsoleBackup.exe, which will allow to run backup from a command line. See more here;

• Added Backup and Restore at Tools - Utilities menu. Available only if SQLite database engine is used;
• Improved mailbox repair options when viewing user mailbox. Now there is a choice to either delete "orphaned" .eml files which may present in the folder, or include them into database, so they can be accessed when retrieving mail;
• Allowed Password length for user accounts increased from 16 to 20;
• The service modules and the user interface now will communicate through named pipe, instead of UDP protocol. It will increase efficiency and avoid data loss;
• Now name of Spam folder, used by SpamAssassin, can be changed (Edit User - Anti Spam tab);
• Starting from this version, outdated authentication methods, such as POP/IMAP before SMTP and Trusted Senders are, by default, hidden. They are not secure and come from old times, when email clients did not support SMTP authentication. They can still be enabled by altering Settings.xml file;

• Communication between the FTP server user interface and FTP service module now is performed using named pipes, rather than through UDP. It should increase efficiency of logging on UI screen.

• Now, Server Greetings for SMTP, IMAP and POP3 protocols, also User-Agent header, sent by web interface, can be fully customized;
• Statistics are no longer getting reset at server startup. They continue count until they are manually reset at Statistics Tab on the user interface;

• For Smart Server, increased the allowed size of username to 255 characters, and password to 200 characters;

• Added support of AbuseIPDB;
• Improved the Mailbox Viewer screen;
• Optimized connection handler. Now users should see less "stuck" connections in TIME_WAIT state;
• More relatively minor changes in the user interface.

• Addressed the problem with "Your License has Expired" error;

• Individual certificates can be used for different domain groups for outgoing mail;
• Fixed a problem with IP address to Geolocation API service. Apparently, they changed the URL.
• Status of services, displayed on the bottom left corner of Mail Server UI application should be working better now.

• Now Domain Groups can be "bound" to specific single IPv4 address. The feature was there, but, apparently, was broken after adding IPv6 support;
• Fixed a bug - Add from a List button was not working at Security - Anti-Spam - Allowed Only Hosts;

• Fixed an error This server was built after your support expiry date.... Apologies to all users who were affected by this.

• Now your registration data can be accessed from Help - My Account;

• Added support of IPv6 addresses (EPRT and EPSV, rfc 2428);

• No significant changes. Updated the UI to be more consistent with Mail Server;

• Further improvements and bug fixes with Web Interface. There are lots of changes. Some of them are:
  • To complay with EU GPRS regulations, added warning about "cookies" Appears on the bottom of login screen;
  • Changed the content of login "cookie". Now it contains just an loging ID, instead of enctrypted username/password (it is safer).
• Now users can have separate logs for each protocol. Makes logs easier to read and analyze. Settings - Options - General - Use Separate Logs.

• Added support of IPv6 addresses to Secondary SMTP, POP3, IMAP and Web services. Running Primary SMTP and Delivery services on IPv6 would cause complications with IP based anti-spam features;
• Now services can bind to All IPv4, All IPv6, or any individually selected IP address(es). In earlier versions they could be bound either to all IPv4 addresses, or just one selected address;
• Refactored most of the code, that handles asynchronous connections. Now server will require less CPU resources and be more responsive. More optimizations are coming;
• Fixed certain issues with Web interface;
• Improved handling of non-unicode messages;
• Fixed minor issues with Recommendations;
• Modified RECEIVED header, so that it includes TLS information (if it was used).

• Added Web Interface. It is a separate Web (HTTP) service, build into the server. It runs along and with the same "rights" with other services (like SMTP, IMAP, POP3), and can be configured the similar way. No third party servers are required. Currently it is pretty limited: you can only check email, and only in Inbox folder. More, including server administration, is coming in future versions. Both, HTTP and HTTPS are supported;
• Improved handling of Recommendations, introduced in version 1.1.5.0: Added checking of server certificate, also verifies whether DKIM key pair is set up properly and they match. Also, if there is an error generating recommendations, it stops wherever error occurs, rather than generating an exception and halting the execution;
• If there is a problem with inserting DKIM Signature, email will be still sent. In previous versions the server was generating and error and not sending the mail.
• Updated the UI for DKIM section. Listbox of domains, which was rather confusing, was replaced by a dropdown list. Also, now you DKIM settings can be tested on the spot. Uses the same method as recommendations, mentioned above.

• Added Recommendations. Tools - Recommendations will generate a report, which will suggest how to improve your settings to optimize delivery to external recipients;
• Added an option to display in clear text passwords for failed connections. May help to track down hackers. See Settings - Options - Advanced - Show "Failed" passwords in logs.
