Is this work ? I can't test solution rtcyrus2.html now (some problem
with downloading mrs-8.12.11.patch and mrs.m4), but I attempt to use 
old http://anfi.homeunix.net/sendmail/rtcyrus-socket.html.

I was install sendmail 8.13.0.Beta2 and cyrus-imap 2.2.3. I can see what
socket map partially work only. A user's existence is verify only:

May 15 16:57:49 smmapd[21219]: executed
May 15 16:57:49 smmapd[21219]: accepted connection
May 15 16:57:49 smmapd[21219]: append_check() of 'user.hsadhjcbvh' failed (Mailbox does not exist)

and I receive bounce from my MX:

==
   ----- The following addresses had permanent fatal errors -----
<hsadhjcbvh at xxxxxxx.ru>
    (reason: 550 5.1.1 <hsadhjcbvh at xxxxxxx.ru>... User unknown)

   ----- Transcript of session follows -----
... while talking to mail.xxxxxxx.ru.:
>>> DATA
<<< 550 5.1.1 <hsadhjcbvh at xxxxxxx.ru>... User unknown
550 5.1.1 <hsadhjcbvh at xxxxxxx.ru>... User unknown
<<< 503 5.0.0 Need RCPT (recipient)
==

Then I to send mail to exsisted but overquoted user I receive bounce 
from end server:

==
   ----- The following addresses had permanent fatal errors -----
<real-user at xxxxxxx.ru>
    (reason: 552 5.2.2 Over quota)

   ----- Transcript of session follows -----
... while talking to localhost:
>>> DATA
<<< 552 5.2.2 Over quota
554 5.0.0 Service unavailable
<<< 503 5.5.1 No recipients
==

Is this the old sendmail's solutions issue or something another ?
