lmtpd don't advertise the "EXTERNAL" auth method

[Balazs GAL]

Hi!

I use a backported version of debian's (thanks hmh) cyrus21 2.1.11-5
package.

My problem is that, lmtpd don't advertise the "EXTERNAL" auth method
on unix socket (neither on tcp). Because it, cyrdeliver (deliver)
can't use the AUTH parameter of the MAIL FROM command (see lmtp_runtxn in
lmtpengine.c), and because it, cyrdeliver (-a auth-id option) and the
mta can't provide the authenticated userid to cyrus. Every post
run as "anyone", so our users cant post to the shared folders etc etc.

2.1.9 and under seems to works fine. (I didn't use 2.1.10)

What's the solution? Can anybody reproduce it?

Thanks

Note,that lmtpd misses the 250-AUTH EXTERNAL line.
