Adding w to the mailer flags tells sendmail to check for users in /etc/passwd before accepting a message. Is there a way to make it check /etc/sasldb or the imap server for existence of the user instead? I found some instructions (search for "OT: sendmail.cf and cyrus" from "Dave Caplinger") in the archives which suggested adding: > FI/etc/mail/imapusers > > LOCAL_RULE_0 > R$=I < @ $=w . > $#cyrus $: @ $1 imap users at mail go cyrus > R$=I < @ $=F . $m . > $#cyrus $: @ $1 imap users at stgt go cyrus > R$=I $#cyrus $: @ $1 imap users go cyrus but this requires keeping the file /etc/mail/imapusers as a complete list, which seems a waste as this information is already stored elsewhere. If there is already something that will list existing users one name per line (as the first whitespace-delimited word, if there is more data then just the username), I could use FI |/usr/bin/thatprogram to get an up to date list. (Or would that only be accurate from the time I load sendmail and miss all updates?) - Josh
