backslash in addresses?

Well, any MUA I had in my hands will gladly accept them.  Among the 
MTA, I know
sendmail accepts backslashes *and* processes them as described (if envelope
address starts with backslash, aliases are not expanded on it).  It also
preserves them when relaying email to another MTA.  I do realize this is
sendmail specific feature, and as it appears from another post in this thread,
not really RFC compliant.

Sendmail uses them.  I'm using sendmail.  It seemed to be simple, clean and
quick solution to resolve one mail-loop problem I had.  Sorry for bothering so
many people for so long time, I just hoped there was a simple way to make
timsieved accept backslash char as part of email address.

Hmmm...  Somehow I got the feeling (from past discussions on the list about
relaxing some other types of checks) that this kind of thing makes it really
hard into official cyrus distribution, even when people love the 
feature.  Plus
this one is specific to single MTA (sendmail), and also very rarely used :-(
