We have a strange problem with our Discourse server. For several weeks the email polling from our internal POP3 server worked without any problems. On February 16th the reception of email suddenly stopped. Strangely, we see activity from Discourse in the log files of our POP3 server:
Feb 25 13:54:49 mailout popa3d: Authentication passed for discourse Feb 25 13:54:49 mailout popa3d: 1545 messages (12060237 bytes) loaded Feb 25 13:54:49 mailout popa3d: 0 (0) deleted, 1545 (12060237) left
However, no new emails are processed.
We are using the newest Discourse version 2.7.0.beta4 (since today 2.7.0.beta3 before). These are our email settings:
Do you have any idea what could be wrong? What can we do to investigate the error further?
