Emails stuck in sending queue are sent several times

Hello, I have a problem with a customer using Outlook for sending emails and I have the impression that something is slowing her email sending process and making their emails to be sent more than one. Have you ever experienced something similar?

  Hey there! The short answer is "no" - I wouldn't expect a tool to send a message multiple times. Can you confirm the message was sent multiple times in the Exim logs? As in, there is a unique transaction for each message?

  I detected this error message in the EXIM log file

  I wouldn't expect either of those things to cause a message to be sent twice. You're specifically looking for a unique mail ID going to the recipient in two separate Exim transactions. If you don't see that, the duplication wasn't from the server side.

  I discovered that "SMTP connection lost after final dot" messages are appearing again in EXIM log files and the associated IPs are related with other messages like these 50416 refused: too many connections 9475 refused: too many connections However they don"t appear at the same time :/

  Right, I wouldn't expect those to be related to this particular issue at all.

  I have just increased the value of the "smtp_accept_max" variable according to this document:
