I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere?

No.

~$ telnet server1.teststable.simplyspamfree.com 143

Try 127.0.0.1 vs ::1

Any insight would be appreciated, thanks!

Proxy/firewall/antivirus/etc in the middle?

If none of that is helpful, set auth_debug_passwords=yes and see the logs.
