Automatically reopen SMTP Connection because of cancellation after 10 minutes

Hi Hasan, first thank you for the super email sender, it is a great simple tool.

I used the Super Email Sender v32.

For the Christmas greetings I sent 2000 emails. It was sent via O365 Exchange Online.

Exchange Online Limits:

Connection inactivity time out: The maximum amount of time that an open SMTP connection with a source messaging server can remain idle before the connection is closed = 10 Minutes

Recipient rate limit: 10'000 recipients per day.

Recipient limit: Customizable up to 1'000 recipients.

Message rate limit: 30 messages per minute.

After sending 250 Emails over smtp.office365.com i got the message "an existing connection was closed by the remote host" an the 1750 other messages could not be send.

In the field "Time Pause Email (sec)" i entered the value 2. Each email took pretty accurate 2.4 seconds and then the connection was broken after 10 minutes.

I tried to change the settings via Powershell and Admin Console in Exchange Online but it seems to be impossible.

Now my question: is it possible to close and reopen the smtp-connection each 9-10minutes automatically?

I'm thinking of whether it might also be possible by being able to choose to take a break after, for example, 240 e-mails to close the connection and re-establish it automatically and then continue to send from that point in the mailinglist where the break is.

Thank you

Markus

Hi Hasan, thank you very much.

Can you explain me shortly where i can activate the feature for reconnecting? I didn't find the option and i still got Error 4.4.1 Connection timed out.

The option is enabled by default, connection timed out, means there is a problem connecting to your SMTP
