Connection to the POP3 server is timing out

Hello Richard, Thomas thanks for your answers.

• we haven’t configured a mail-receiver and manual polling is disabled
• we are using POP3 and POP3 polling is enabled

So I’ve only configured one (POP3), not both.

• I’ve got nothing in production_errors.log for the past 5 days.
• Nothing special on production.log, no occurance found when searching for mail or Mail
• I don’t see any pending mail

In the dashboard I can see that last received mail is 19 hour ago and I can find the corresponding msg in the topic.

The only abnormal thing is this :

We are receiving a mail over and over again on the noreply mailbox used by the server which translated to English would be something like :
From : “Auto-reply from xxx@xxx.xxx” xxx@xxx.xxx
Subject : Answer. : [ForumName] email problem - Automatic answer
To : noreply@xxx.xxx

Hello, can you take note of my new email adress xxx@xxx.xxx. My xxx address is not in service anymore.

We have received this mail everyday starting from the 19/11 and we’ve just handled the problem today by changing the mail of the account with the new one.

In the received section I can see many mail from this user. But don’t see any msg from this user on the corresponding topic pages. Message have status : Email::Receiver::AutoGeneratedEmailError

Could it be this bad mail linked to an account that cause the problem?

Thanks
