Once again, this would appear to be a server configuration issue, not a GnuPG issue.

If it is possible for someone to easily spoof a user's credentials and access
their emails, then it's an authentication issue. If you're worried about
eavesdropping on the wire, you want SSL or TLS to secure the link.

In the case given of IMAP, you want  IMAP + TLS or IMAP + SSL

Check with your server admins to determine if your server supports IMAP w/ TLS
or IMAP w/SSL. POP3 and SMTP also may be configured to use one of these suites.

If these are supported, you may select them on the 'Server Settings' tab in
'Account Settings'

It sounds as if you need to sit down and realistically evaluate your security
needs with those who administer your network and servers.  If your threat level
is such that you do not feel the existing tools can meet your needs, it's time
get out your checkbook and call in a professional not continue to seek free
advice on a mailing list.
