However, in these specific cases, I'd prefer thatthe connection goes through to dovecot, but for dovecot then to always generateauthentication failures for those specific connections ... even if a validuser ID and password happen to be specified.Is there a way to do this in dovecot?Thank you very much in advance.-- hippo...@gmail.com Take a hippopotamus to lunch today. .---------, 0__0 / ( oo'---, / oo\ ,\ | | \ ,=__/ \ / / /------| /| |__|-' |__|' _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
