Hi Bartek, is TESTOWA_LISTA_MEJLINGOWA the list name that you are trying to post to? If so, it sounds like you have some other program than SMTPL listening in on port 25. Is there an SMTP server on the PAYRANKINGS.COM server? If so, special setup is needed and you should follow up on the LSTSRV-L list, which is for LISTSERV administrators, not on the LSTOWN-L list, which is for list owners, and most people here are not involved in setting up the server itself, just in the operation of the lists. -- Francoise Becker There is only one LISTSERV(R) -- the product that launched the email list communication industry in 1986.
