Additional note:
I’m unable to reproduce the issue either! On several other servers, this message does not appear, and at first glance, the configuration seems to be the same everywhere.
On those servers, the error only occurs when no emails are present, maybe once or twice a month – if at...
Am I understanding correctly that if I subscribe to the support plan, I will be charged €10 per month – and if I cancel the subscription after one month, I only pay for that month? And if I need support again in a year, I can simply re-subscribe without having to pay for the months in between or...
