With 4.82 RC1 and the dovecot authenticator in PLAIN mode, Alpine (which uses the UW IMAP C-client) fails at SMTP authentication. A manual test revealed a tiny change in the SMTP dialogue. Exim 4.80.1: C: AUTH PLAIN S: 334 C: <base64-string> S: 235 Authentication succeeded Exim 4.82 RC1: C: AUTH PLAIN S: 334 NULL C: <base64-string> S: 235 Authentication succeeded Notice that the actual authentication succeeds in both cases. However, RFC 4954 doesn't allow the non-empty 334-reply. The C-client is very strict about this and immediately aborts the authentication attempt when it sees the "NULL". -- -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
