We are currently experiencing email service access issues affecting mainly the Runbox webmail. The cause is related to the adjustments made to resolve IMAP/POP specific access issues (see separate issue) and we are currently working to stabilize operations.
We apologize for any inconvenience caused and except the issues to be resolved shortly.
UPDATE 24.11.2022 18:30 CET (12:30 PM EST): We have adjusted authentication database configurations to increase the capacity of the authentication service, and we expect this to help prevent further access issues going forward.
