Not to my knowledge. Could you post for future reference which cyrus-imap
versions are afected by it ?

After analyzing (more seriously) code in cyrus-imapd-2.2.6 (switch after
accept in service-thread.cfile ) I think that it will do what I requested.
For "other errno codes" it executes among other things:
syslog(LOG_ERR, "accept failed: %m")
[ where %m is replaced by string produded by strerror(saved_errno) ]
