服务器有多少活跃的 IMAP 账号？是不是达到 imap 连接数限额了？尝试调大 imap 连接数。
活跃IMAP帐户约有120左右,我已更改以下设置,问题还未解决.
protocol imap {
mail_plugins = $mail_plugins imap_quota autocreate imap_acl
imap_client_workarounds = tb-extra-mailbox-sep# Maximum number of IMAP connections allowed for a user from each IP address.
# NOTE: The username is compared case-sensitively.
# Default is 10.
# Increase it to avoid issue like below:
# "Maximum number of concurrent IMAP connections exceeded"
mail_max_userip_connections = 200
}
