net_imap, net_smtp: Problems with Eudora 7.1.0.9

Some incompatibilities noted while testing the BBS email servers (IMAP and SMTP, but not POP), with Eudora 7.1.0.9 on Windows 7. SSL connections did not work at all out of the box for me so these are only with plain text connections.

I know Eudora hasn't been updated since 2006, but these are generally issues on the server side, not with the client.

Trying to get the mailbox structure (IMAP) - stuck in infinite loop until cancelled:
