Recently my IMAP server started erroring out when using KMail with such error: Login failed, server replied: A000004 NO Too many open connections (50 of 50 for ...) Support suggested to reduce the setting that limits cached server connections. Thunderbird has something like that. See: https://support.mozilla.org/en-US/questions/1082511 I tried to find such setting in Kmail / Akonadi, but didn't find one. Is it possible to configure and if not, can such setting be added? My current setup: * Kmail / Akonadi: 22.12.3 Thanks.
