Free termination software for windows

XMail 1.26 is a useful utility which provides you an Internet and intranet mail server featuring an SMTP server, POP3 server...etc

This server born due to the need of having a free and stable Mail Server to be used inside my old company, which used a Windows Network.

Major Features:

1. SMTP server
2. POP3 server
3. Finger server
4. Multiple domains
5. No need for users to have a real system account
6. SMTP relay checking
7. RBL/RSS/ORBS/DUL and custom ( IP based and address based ) spam protection
8. SMTP authentication ( PLAIN LOGIN CRAM-MD5 POP3-before-SMTP and custom )
9. A POP3 account synchronizer with external POP3 accounts, account aliases
10. Domain aliases
11. Custom mail processing
12. Direct mail files delivery
13. Custom mail filters
14. Mailing lists
15. Remote administration
16. Custom mail exchangers
17. Logging
18. Multi-platform code.
19. ESMTP/ESMTPS server
20. POP3/POP3S server
21. Custom SMTP maps check
22. SMTP protection over spammers (IP based and address based)
23. SMTP ETRN command support
24. Account aliasing
25. Domain aliasing
26. Locally generated mail files delivery
27. Multi platform (any Windows and almost any Unix OSs)
28. Fine grained message filters
29. Custom (external) POP3/SMTP authentication
30. TLS support for SMTP and POP3, both server and client side
    

Enhancements

• Added the ability to select SmtpConfig-IP options by local port too (SmtpConfig-IP,PORT).
• Added a new -YT command line option to set the timeout used by a POP3 client connection.
• Fixed a bug in the RFC822 ATEXT token definition.
• If the recipient domain does not have an MX record, and does not have an A record, now XMail bounces immediately.
• Fixed OpenSSL connection shutdown to avoid RST packet generation.
• Changed SMTP AUTH LOGIN authentication to support the optional inline parameter.
• Added IPV6 support. New command line options are available to select XMails behaviour with respect to IPV4/IPV6 compatibility.
• Fixed/strengthened RFC address parsing.
• Drop the SMTP connection is case of timeout.
• Fixed a bug caused by the new strict host/doman name check added in 1.24 (in the SMTPGW.TAB parsing).
• Completely changed the DNS resolution code.
• Do not try the A-record delivery in case of temporary DNS/network errors.
• Added remote MTA message ID to SMAIL logging.
• Added a new ``PO
• Fixed a bug where STARTTLS was resetting the session too much, by canceling certain flags/options read inside the SERVER.TAB.
• Fixed a bug that happened if a message filter mistakenly remove the message file from under XMail control.
• Fixed a bug that make XMail to wrongly report virtual memory sizes on 32 bit systems with larger than 4GB VM space.
• Changed the line termination used to store messages into the mailboxes of Unix versions of XMail. Now messages are stored with the OS native LF termination, instead of the RFC CRLF that was used before. This allows other Unix softwares working together with XMail to not be confused by the extra CR present in the line termination.
• The "smtprelay" behavior with respect to 5xx responses from one of the servers in the relay list, has been changed. Now a 5xx response will stop the processing, instead of iterating on the remaining servers of the list.
• Avoid to crawl all the USER.TAB file during a "userlist" CTRL command.
• Fixed a bug that allowed non-RFC characters inside domain names.
• Fixed OSX Leopard build error.
• Added "timeo" option to flags execution.
• Added "NoAuth", "EnableVRFY" and "EnableETRN" settings inside IP properties.

SVC Filter Designer 2.09 is a powerful design and analysis program which helps you expedite the design and analysis of lowpass (and highpass) filters with nearest 5% component values.

Major Features:

1. A 32-bit electrical filter design software nicely written to help the radio amateur, technician or engineer design and analyze lumped-element lowpass and highpass filters.
2. Order, topology and family are all entered by clicking on buttons.
3. If the Chebycheff or Cauer family is chosen then three options for passband ripple (.01, .044 and .200) are available.
4. If the Cauer family is chosen then four options for stopband depth (30, 40, 50 and 60 dB) are available.
5. Cutoff frequency is entered in the usual text box and can be from audio through UHF.
6. Cutoff frequency can be as low as 0.1 Hz, allowing the value of .159155 [ i.e., 1/(2*PI) ] to be used. This, in conjunction with a termination value of one ohm, yields parts values for the textbook classic "normalized" design.
7. System impedance by default is 50 ohms but a textbox allows entry of any value of your choice, for example 600 ohms for audio.
8. Inductor Q values are set by default to a value of one million. A textbox allows entry of any value of your choice in the range of 10 minimum to one million maximum.
9. The graphic output draws the schematic of the filter you have designed, and also plots the responses of that filter (both transmission and reflection). It selects the nearest 5% values for the capacitors and shows those values as well as the exact values and overlays the response plots for the nearest values on top of the original exact-value plot.
10. Tuning buttons allow stepping the cutoff frequency up or down in 1% steps and immediately seeing the new performance of the redesigned filter on the plot.
11. Place the cursor anywhere on the plot and see the transmission, reflection, VSWR and envelope delay values for that frequency.
12. Inductors are retuned as necessary to maintain the response of Cauer filters after nearest capacitors are chosen.
13. To maintain the high level of quality of the graphic output, the outputs to the printer are not "screen dumps" but instead are from a set of dedicated routines which write directly to the printer. The quality of the graphics as delivered by the printer will be limited only by that printer, commonly several hundred pixels per inch. The printer output on one sheet contains the schematic with parts values along with the set of responses.
14. Click on the "Write Elsie File" button to write a file to drive Elsie the filter design and analysis program for followup filter examination in even greater detail.
15. Click on the "Write Spice schematic" button to write a file to drive the LTspice simulator. (Tonne Software has no connection with Linear Technology Corporation.)
16. This program was written to simplify the sometimes difficult task of lumped-element lowpass (and highpass) filter design by automating or setting as default some of the more frequently-encountered options. But it also includes analysis, uncommon for such an application.

Enhancements:

• Upgrade Design page appearance
• Improve Spice schematic file writer
