I have the following recipe
:0fc
* $^From:.*(${RECIP_REGEXP})
| formail -a "Reply-To: gourous(_at_)eleves(_dot_)ens(_dot_)fr (Compte Gourous)"
which is meant to insert a Reply-To: line in messages coming from
certain people. It works very well most of the time, but once in
a while (several messages a day go through this recipe, and the error
accurs about once per month) I get the following error:
procmail: Extraneous filter-flag ignored
procmail: Error while writing to ""
procmail: Skipped "| formail -a "Reply-To:
gourous(_at_)eleves(_dot_)ens(_dot_)fr (Compte Gourous)""
Obviously something went wrong with the pipe, but what ?
Isn't it possible to get more explicit error messages than
`Error while writing to ""' ? (I recently added VERBOSE=on,
but the error has not occured since then, and I do not expect
this to change the error message anyway).
I assume that the `Extraneous filter-flag ignored' is just an
artefact and was issued because formail did not output any data,
but this is misleading too.
I found a similar problem mentioned in the list, but the answer
was not very satisfactory:

Do you have 3.11p7 ? If not, upgrade. The recipe work danady there.
I have only 3.11pre4, so this may be the reason, but I do not
want to blindly upgrade and just hope that my problem will
disappear ! So, is the problem I mentioned a known bug that has
been fixed, or at least are there in pre7 more explicit error
messages concerning pipes ?
