If you are using the v1.0.4.3, built of February 27, please download the February 29 release, and upgrade again, as described here.

In the Feb 27 version, in case Bounces From address is not specified, bounced emails may go into an endless loop.

Sorry for inconvenience

Mail Server

Changes in this version are significant

• In case of multiple IP addresses, each domain group can have associated IP address, and it will respond differently on requests to different IP addresses, displaying different greeting at SMTP connection, or binding to specific IP addresses when relaying mail, using different default domains and so on...; See this document for more.
• Added support of Domain Keys - another security/antispam measure, which ensures that emails originating from a given domain are approved by the domain; If you need to set up domain keys for your domain, see our Domain Keys Setup Wizard;
• Added SMTP greeting - the information can be appended to the standard greeting issued by the server;
• Optimized address verification - if SPF result is "pass", then it will be not performed. It would save resources.
• SPF has an additional option - not to reject mail, just add SPF-Received header;

Web Interface

• Added View/Hide Headers option when viewing an email message;
• Changes regarding "bound IP addresses" have not been reflected with the web interface at this point;

Mail Server

• Starting from this version, we wil be using new validation method. All registered users will receive new license file before March 4, when this new version stops working using older codes. This method makes it nearly impossible to use "fake" regitration codes... :-)
• If user selects an option to accept junk mail to "Junk" folder, mail will not rejected, but will be placed in that folder. Before this feature was working only for individual filters, now it will work even for global anti-spam features, such as SPF, Reverse PTR, DNSBL, Filters and Attachment Filters. It will work ONLY when mail is sent to a single local user, and that user has "Place Messages in "Junk" Folder" option enabled;
• Fixed a bug with reverse PTR matching, it was not working;
• Mask of the datetime entries in the log can be changed from Options - General
• Added Database Command box to the Tools - Utilities. It allows to issue any SQL command to the database;
• Fixed a problem with messages hanging when being delivered to blank recipients;

Web Interface

• Fixed handling of forwarded messages with attachment. Now messages have relatively simple structure, they will be not included as "forward.eml" attachments;
