Hi Ken, thanks for the feedback.

I thought the same as you & Philip, but if I remove pre-auth, then lmtp 
offers no AUTH mechs at all. This is why I think I've got something 
wrong on the lmtpd side, mail always fails without pre-auth so that's 
why in the past I've just had it enabled. With pre-auth, mail is 
delivered, but I cannot get authenticated_sender to appened AUTH= 
without some lmtp mechs it likes which I imagine is any mech apart from 
pre-auth. I can't  find a way of setting up lmtpd with mechs.
I've seen postfix guys setting up lmtp auth'ing to cyrus, but no hints 
about how to setup the lmtp mechs themselves. I obviously have an 
understanding gap somewhere, so I need some info about which mechs and 
how to set them up for lmtpd.

I compiled cyrus 2.2.3 with only the configure option --with-saslauthd ; 
should I use anything more ? When I used the debian package for 
cyrus2.1, I still had this problem with authenticated_sender & lmtpd, so 
I don't think its a problem peculiar to my compilation, but I'm no cyrus 
expert. I've usually just used the debian packages but I in this case I 
needed virtual domains so I had to compile 2.2.3 myself.


ciao
