Why does Claws Mail load big folders slowly?
Certain options, although handy, can slow down Claws Mail. Consider disabling the following options to achieve more speed: /Display/Summaries ‘Display sender using address book’ /Display/Summaries ‘Thread using subject in addition to standard headers’ /Plugins/GPG ‘Automatically check signatures’ In the Message List, Sort by Date or other non-string headers instead of Subject, From or To. Avoid using cpu intensive folder Processing rules conditions such as “Whole message”, “Body part”, etc, and Pre/Post processing.
