Is a capital letters title for this ML blocked? - Mailing list pgsql-general

Hi all,

I don't know who's the list owner but I'm trying to post a message with
the subject being:

EXECUTE + transaction = unexpected error -8
(exciting, isn't it?)

But it seems not to arrive here and I receive no refusal message. Can
somebody tell me something (this e-mail is also to check that my e-mails
are still received :-))

Thanks,
Yannick
