Mail Server v1.0.8.3

Sun, 06 Nov 2011 18:10:34 GMT

Added support of STARTTLS (STLS) command for SMTP, POP3, IMAP, and SMTP relay and delivery, which will allow secure, fully encrypted connections, when possible;

Mail Server v1.0.8.2

Sat, 08 Oct 2011 23:59:35 GMT

Optimized delivery speed. In earlier versions each "tick" which was checking whether messages were in the outbox queue, was picking up only one message at a time. Now it will attempt to pick MaximumAllowedThreads-ActiveDelivery threads messages, which should considerably increase deliver speed;
Optimized SEARCH and STATUS IMAP commands. They appear to be used very extensively by Android, and (not that extensively, but still) by iPhone. Now users who use mobile phones to access their IMAP accounts will see considerable improvement;
Optimized STORE IMAP command. Before storing of IMAP flags was occuring one message at a time, which seemed to be fine with SQL server, but proved to be slow for SQLite... Now it happens with single SQL call.

ArGoSoft Mail Server v1.0.8.1

Tue, 07 Jun 2011 01:33:36 GMT

Fixed a bug: when using IMAP via Firefox with "When I delete a message, move it to Trash folder" option, marking messages in the trash folder was causing high CPU usage, and was taking some time, making the server pretty much non-responsive. The problem was happening only when using SQLite.

ArGoSoft Mail Server v1.0.8.0

Mon, 23 May 2011 21:53:55 GMT

Fixed a problem with web interface - was showing only first page of messages, and would not switch to other pages; In order to fix the web interface, mail server itself has to be updated;
When installint initially, was still using SQLite, even when SQL was requested;
There was a problem with switching from SQLite database engine to SQL server database engine: the SQL database was not being created;

ArGoSoft Mail Server .NET v1.0.7.9

Wed, 27 Apr 2011 01:47:25 GMT

The server no longer requires Microsoft SQL Server. If SQL server is not found, it will use SQLite engine, which does not require separate installation. If SQL server is found, then user will be prompted whether he wants to use it;
Made other improvements, such as, now mailbox rebuild indexes orphaned records, rather then deleting them, also added an opotion to increment UIDL validity of folder (both on the Mailbox viewer box);
Made minor improvements on web interface;

Mon, 17 May 2010 23:35:28 GMT

Mail Server v.1.0.7.7 is now out.

There are no changes in Web Interface.

Previous version (1.0.7.6) of mail server caused problems with users, who had SImple SMTP option disabled on the Options - Server Options - SMTP page. This version fixes the problem.

Mail Server 1.0.7.6 - fix for loaded servers

Wed, 12 May 2010 02:07:23 GMT

Mail Server

Improved handling of lenghty SMTP connections. New method should eliminate problems with "stuck" SMTP connections, which waere causing high CPU load and, eventually, server crash on heavy loaded servers;
Now individual domain groups can be exported and imported. Useful when splitting server between several computers;
Fixed several minor problems;

Web Interface

Fixed several problems with displaying complex messages on the web interface;

Mail Server v1.0.7.5

Thu, 25 Feb 2010 17:49:41 GMT

Mail Server

Hopefully fixed a problem which was causing mail server to stop

Web Interface

Web interface now will work with Safari;

Mail Server v1.0.7.4

Sun, 21 Feb 2010 23:10:28 GMT

Mail Server

SMTP now supports two methods of authentication: AUTH PLAIN and AUTH LOGIN;
Improved the way how "stuck" delivery threads are getting cancelled. In some cases with previous versions they could stay connected infinitely long;
If a domain is in greylisting exception, and SPF is PASS, DNSBL will be not checked - to avoid blocking messages, when single IP addresses belonging to large ISPs are blacklisted by DNSBL databases;
Now there is an option to check all IP addresses, referred to in RECEIVED headers, against DNSBL databases;
If autoresponder is enabled, and return address is not specified, now the server will use username, plus @ symbol, plus either the first domain in the list belonging to the domain group, or domain group name itself;
If SMTP for account is disabled for an account, connection will be still accepted, if it comes from web interface;
If there is an unsuccessful attempt to log into the POP3 or IMAP server, or perform uncussessful SMTP Authentication, and entry is created in the Windows application log;

Web Interface

Fixed a problem with messages, containing embedded images with same name - was giving Resource already in use error when displaying images;

Mail Server v1.0.7.3

Sun, 03 Jan 2010 22:36:30 GMT

Mail Server

In previous versions "stuck" IMAP connections were not getting disconnected, because it was assumed that IDLE command can "stick around" infinitely. It turned out, some clients (e.g., iPhone and iPod) do not use IDLE command, but still leave connections open, which causes open IMAP connections to add up. In this version IMAP connection gets periodically checked, along with POP3 and SMTP connections, and gets disconnected, if it was around for long time, and currently is not in IDLE state;
Fixed a bug in Archiver: copy function was copying entire folder, not just a selection;
If a list of trusted or banned hosts contained blank entry, it was returning false positives. Now blank entries are just removed;
If remoting service cannot start, now it not affect other services. Before it would crash other services too;
Added View Log Folder option to the mail server UI;
Now catching exception when reading server start date/time. It appears, server startup times was not getting stored properly into the Settings.xml file on non-English versions of Windows;
License is now checked onlny at server startup, rather then during each connection. It appears, decrypting of the license and checking it's signature was taking pretty long time on some systems;

Web Interface

Fixed a problem with processing MIME messages, when part separators (boundaries) contain space;

When deleting users, SQL command timeout increased from 30 seconds to 5 minutes. Was causing SQL server timeout when users had tens of thousands of messages;

Users, domain groups and mailbags can have individual settings for nine anti-spam features supported by our server. Settings may be inherited from the "above" level, or overriden;
Added Trusted Senders - you can specify senders (email addresses), and if the value transmitted with RCPT TO SMTP command matches one of them, connection will be considered as trusted. We do not recommend to use this option, we added it for backward compatibility;
Fixed an Object Reference not Set on Object errors when mail was sent to non-existing domains. This error was not causing any problems, was just showing in the log, causing confusion;

Added buffered output to IMAP. It turns out, that some firewalls are corrupting data, if it is sent in small chunks. Buffering allows to avoid these problems;
Optimized database cleanup procedure at server startup. When DNS cache was large, removal of expired records was causing database server timeouts, and server was not starting up;

Replies to UIDL and LIST commands in POP3 now are getting sent in a "single batch", rather then line by line - significantly improves performance;

Mail Server v1.0.6.3

Tue, 14 Apr 2009 15:14:23 GMT

IMPORTANT: If you are using the web interface and/or other optional modules, modules you use also must be upgraded!

Mail Server

Fixed a problem with mailbox usage calculations;
Fixed a bug with custom bounce messages;
If during reception, message size exceeds the maximum allowed size, the server will wait until entire message is received (without allocating additional memory), and send back a rejection error message only after sending MTA is done with transmission. In earlier versions server was sending error message without waiting for end, making delivering MTAs assume that there was just a transmission error, and making them to do multiple retries to deliver large messages;
When checking reverse PTR records, in case lookup fails will assume PTR record does not exist;
Fixed a problem with Outlook Express in case email addresses of senders contained illegal characters. Outlook Express was just skipping them when accessing a mailbox using IMAP;
Connectio monitor frequency is now configurable (Options - Server Options - Advanced);

Web Interface

There are no significant changes, but it must be upgraded to keep shared libraries syncrhonized with the mail server;
