In your description, you say you're trying to use the account 'cyrusadmin'. In your example code you use 'user'. However, your imapd.conf will only allow 'cyrus' and 'pilsl' to connect to your lmtpd.
You need to have the account you are trying to login as listed as an administrator. Either include it in the 'admins' line, or, if you don't want the account to be a general administrator, add an 'lmtp_admins' line. Cheers Chris Peter Pilsl wrote: > >the syslog.
