I found in /var/log/messages some instances of this: imapd-ssl: Maximum connection limit reached for ::ffff:10.0.0.1 It appears that the default configuration for MAXPERIP (maximum number of connections to accept from the same IP address) was set to 4. (I assume it's the default, since I never changed it myself.) Changing the value to 10 eliminated the Thunderbird problem entirely. I don't know if some other value between 4 and 10 would work as well. I'm happy with it as it is now. -- Jim
