ok, found that on SuSE lists and I think it is what I am talking about. I am
quoting the conversation between a user and the author of BincIMAP:

Hmm, I've been and had a look at the RFC and it's not entirely clear to
me.
>From RFC2060 in section 9 "Formal Syntax":
flag_list ::= "(" #flag ")"
flag ::= "\Answered" / "\Flagged" / "\Deleted" /
"\Seen" / "\Draft" / flag_keyword / flag_extension
And also:
The following syntax specification uses the augmented Backus-Naur
Form (BNF) notation as specified in [RFC-822] with one exception; the
delimiter used with the "#" construct is a single space (SPACE) and
not one or more commas.
>From RFC822 in section 2.7 "#RULE: LISTS":
A construct "#" is defined, similar to "*", as follows:
<l>#<m>element
indicating at least <l> and at most <m> elements, each separated
by one or more commas (","). This makes the usual form of lists
very easy; a rule such as '(element *("," element))' can be shown
as "1#element". Wherever this construct is used, null elements
are allowed, but do not contribute to the count of elements
present. That is, "(element),,(element)" is permitted, but
counts as only two elements. Therefore, where at least one ele-
ment is required, at least one non-null element must be present.
Default values are 0 and infinity so that "#(element)" allows any
number, including zero; "1#element" requires at least one; and
"1#2element" allows one or two.
So here it says that null elements are allowed but are ignored. Above it
said that the separator was a single space not one or more commas. So it
appears that (\SEEN ) could be valid because it only uses one space,
even if it does have a null element on the end. Or is there something
that clarifies this?
Cheers,
Martin.
You're referring to RFC2060, which was obsoleted in March 2003 by RFC3501.
flag-list = "(" [flag *(SP flag)] ")"

Could you please have a look and let me know, as my knowledge about the
internals of Horde and IMP is very limited?
