Patch to fix above.
Balsas libnetclient/net-client-pop.c never adds NET_CLIENT_POP_AUTH_USER_PASS to the list of authorisation methods as qmail does not support the CAPA command.
The response to the CAPA is command is "-ERR Authorizaion First"
Patch attached. Its probably ugly but it works for POP3 and POP3S.
can you report this to upstream too?
Is this still relevant with balsa-2.6.1? If so, what is the upstream issue report link?
Seriously, noone should use qmail-pop3d.
