SMTP Werkzeug changelog

Changes in 1.5

Two new send types: EICAR (plain text message with eicar.com attached) for testing antivirus protection, and GTUBE (plain text message containing GTUBE) for testing SpamAssassin anti-spam protection
The current send type is now indicated in the window by an icon, as an extra reminder of just what you will be sending
Sender display name can now be customised in Options, as can the test message subject
Test type is now selected by radio button instead of popup menu, for speed
Test type selection is now remembered between program sessions

[Fix] Return-Path header removed, since MUAs don’t send this header!
[Fix] Send progress label implemented as a new off-screen buffered label to cure the abominable flicker

Creating a blank file “SMTP Werkzeug preferences.xml” next to the executable enables portable mode
Message serial added to the message subject to help identify bounce messages
[Fix] Off-by-one error in the transcript highlighting during payload messages (another bug caused by text boxes using CR instead of CRLF under Windows)
[Fix] HTML message serials were out by one

Custom MX servers can now be specified in the new Options dialog box, and will be populated upon launch; this dialog box also exposes the previously undocumented preferences for controlling transcript colours and custom nameserver
The Options button is now named “Test options” to distinguish it from Tools → Options
Session history window which records a summary of session activity
The destination mail server is cited by both its name and address in test messages (this undoes a regression due to the revised DNS lookup implementation, although previously only the name was given)
[Fix] Test message type summary is no longer mistakenly shown when closing the test options if the test type dropdown is not set to “Deliver test message”
[Fix] Test type pop-up menu now focused with alt+Y instead of alt+T, as the latter now belongs to the Tools menu

Added Tools → Copy MX records to place the current MX records into the clipboard (with priorities)
IP address resolution is now a separate step in the test process, to catch mistakes where an A record has been set incorrectly or is unexpectedly being overridden by a hosts file entry or local DNS
Added an update check button to the About window
Added a menu bar, to make the About window more discoverable
[Fix] Better dialog box placement for all but messageboxes
[Fix] Removed a bug where the dropdown menus would sometimes forget an address
[Fix] 48×48 icon was iffy

The last ten sender and recipient addresses are remembered
Approximate message size included in MAIL FROM for servers that advertise SIZE; for payload (arbitrary size) messages, the reported size is n + 1 payload blocks (where each block is one copy of Jabberwocky)
[Fix] Styled text is no longer incorrectly pasted into plain text fields
[Fix] Cut and Paste context menus no longer available on disabled text fields
[Fix] Paste context menu command for plain text fields now does the work itself, as REALbasic’s Paste() function was pasting the empty string instead of the clipboard contents in some cases
[Fix] MX button is no longer mistakenly disabled along with the Begin test button
[Fix] Payload messages incorrectly used “name” instead of “filename” to describe the attachment name
[Fix] Authorization ID now omitted in PLAIN authentication due to a very weird instance of “501 malformed auth input (#5.5.4)” from my own domain’s server when handing it a particular set of credentials

[Fix] Removed stray debugging statement
[Fix] Authentication enabled setting is no longer committed to the preferences, for convenience

SMTP LOGIN and PLAIN authentication
All message types now include a serial number (since the program was launched), send date on the local computer, and selected MTA, for diagnostics purposes
[Fix] Messages sent under GMT/UTC now correctly use “+0000” instead of “0000” for the time zone offset
[Fix] Pressing Ctrl+C to copy text no longer submits the dialog (a bug in REALbasic—Ctrl+C misreported as ASCII 0x03 in KeyDown—discovered by trying to work around another bug in REALbasic (where pressing Return (0x0D) or (keypad) Enter (misreported under Windows as 0x03, as on a Macintosh) causes an error alert sound)
[Fix] Within the test (message) options dialog, Alt+S now correctly selects the text of the message size text box

Additional MIME headers generated for improved standards compliance
Two new test message types: HTML (using an in-built test message) and payload, which streams a message of any given size to the destination server
[Fix] Program name spelt correctly in the plain-text message

Coloured text in transcript
Cancel
Autoscroll (not intentional, just a side effect of the highlighting)
[Fix] No longer shows “Disconnected”, although out-of-order transcript lines cannot be avoided
[Fix] Copy All uses the correct line endings, though it does not copy the text in colour; use Select All then Copy for that
[Fix] Removed the annoying beep when pressing enter
[Fix] Begin test button was not kept disabled until all valid values were present
