  • Improved: Error handling for extremely large emails that cannot be read in one piece

December 14, 2015

  • Improved: New version allows email addresses with a name part ending on a minus sign (user-@domain.com) because some servers actually do accept these addresses even though they are not correct by the original email RFC's.

September 22, 2015

  • Improved: Prevents application exception caused by giant-sized emails and by extremly deeply levveled emails in the ndr queue caused by emails going round in circles through forwarding

September 08, 2015

  • Improved: Allows recipient email addresses with underscore character ("_") as last character of name part of email right before the @ (not actually allowed in RFC standards but sometimes still used)

August 11, 2015

  • Improved: Now accepts oddly formatted MAIL FROM commands without <> brackets around email address

July 18, 2015

  • Improved: Subject line in non-deliverable reports now shows reason the email could not be delivered

July 08, 2015

  • Improved: Admin tool automatically reconnects to background service in case connection is lost (i.e. if MultiSendcon service is restarted)

July 03, 2015

  • Bugfix: Some dialogs had misaligned fields after the last update - corrected

June 15, 2015

  • New: Now can replace SMTP envelope sender (MAIL FROM) with fixed sender email but leave the sender address in the email itself the same.

May 29, 2015

  • New: Passwords are now stored encrypted (AES standard) in the .cfg configuration file.

May 27, 2015

  • Bugfix: Formatting of NDR emails corrected.

May 21, 2015

  • New: Emails that are sent to multiple recipients are no longer split into individual emails to each recipient when send via SMTP relay servers but instead are forwarded as only one email with multiple recipients.

March 13, 2015

  • New: SMTP timeout can now be configured for each account (instead of fixed 30 sec. timeout)

March 10, 2015

  • Improved: No hangs dealing with temporary email files that are blocked  by some external virus scanning etc.

February 25, 2015

  • Improved: Now removes original email from NDRs if original too large to be accepted

  • Improved: Better error message if SMTP server returns verbose error message with html code

  • Improved: Now allows internals.log file to be switched off for data protection reasons

  • Bugfix: 45x "temporary" smtp error codes could cause emails stuck at 5 minute retry interval - now using normal retry limits

  • New: Now log file options on advanced config screen to allow daily log files and log file size limits to be changed

  • In Admin Test-Email now says [no connect] instead of just result code 0 when smtp relay server can't be reached

  • Disposition-Notification-To header now with <> around the email


January 14, 2015

  • New: New "advanced" configuration page with new parameter "limit concurrent sending threads". MultiSendcon uses multithreading to send multiple emails at the same time when many emails are in the queue. Some SMTP relay servers reject emails if too many concurrent connections are open. use this new limit to keep MultiSendcon from overloading your SMTP relay server.

January 09, 2015

  • Improved: Problems with Multithreading solved when sending Emails with many recipients

December 17, 2014

  • Improved: Connectivity with SMTP servers needing explicit SSL on port 465´

  • New: Special handling of smtp error message "421 Too much load": Will not limit retries for this message

November 06, 2014

  • Bugfix: Problem with parallel processing many retries or many NDRs at the same time solved.

September 10, 2014

  • Improved: Replace-Sender feature now also replaces Disposition-Notification-To header field so read notifications are sent back to the correct address

August 29, 2014

  • Improved: Prevents problems of previous versions when configuration is updated and simultaneously new emails are sent in.
  • Improved: More information logged in special log file for TLS/SSL connections

August 21, 2014

  • Improved error handling in case something (i.e. antivirus) blocks access to the temporary email files that MultiSendcon maintains. 
  • New: French language added
  • New: Portuguese language added

August 14, 2014

  • New: Lets you specify a default sender address for emails that Exchange sends out with emtpy sender spec <> like out of office messages or non delivery reports. 
  • Improved: Fine-tuning of limits to concurrent threads for mass emailings.

May 08, 2014

  • Melhoria: agora também aceita codificação de 8 bits em e-mails no caso de os caracteres especiais serem codificados como caracteres de 8 bits em vez de caracteres HTML.
  • Melhoria: o software agora limita automaticamente o número de threads simultâneos de mensagens em massa, para não sobrecarregar o processamento

May 06, 2014

  • Melhoria: a comunicação entre o MultiSendconAdmin e o serviço teve alguns limites de tamanho impostos pelo Windows Communication Framework, o que tornou as configurações com mais de 50 contas impossível. Nós aumentamos essas restrições para que agora sejam possíveis configurações com vários milhares de contas.

April 18, 2014

  • Novo: tempo de espera configurável para cada conta para abrandar o rendimento dos servidores de retransmissão que não permitem mais do que um determinado número de e-mails por hora
  • Novo: o MultiSendcon agora usa multithreading para enviar vários e-mails ao mesmo tempo e, assim, aumentar o desempenho
