There is usually "no limit" from cyrus side (except you have some untypical low limit for maxchild on imapd in cyrus.conf) Thunderbird seems to get problems when i.e. larger IMAP structures (many folders) exist / has to be "displayed" / "synced" with its local cache. We typically "solved" that by increasing the amount of "maximum IMAP connections" in Thunderbird (i.e. doubling it). see i.e.: https://www.siteground.com/kb/you_may_have_exceeded_the_maximum_number_of_connections hth, niels. -- --- Niels Dettenbach Syndicat IT & Internet https://www.syndicat.com PGP: https://syndicat.com/pub_key.asc --- ------------------------------------------ Cyrus: Info Permalink: https://cyrus.topicbox.com/groups/info/T89c3eaa86d49a212-M1ecc476ffc852e47e27b7dc9 Delivery options: https://cyrus.topicbox.com/groups/info/subscription
