Hello list,
I have 2 users sending email from cell phones and using their Qmail Toasters as outgoing mail servers. It seems that somehow the cell phone company, Verizon and Sprint in these cases, is somehow implementing an intermediary server between the Toaster and the cell phone. This intermediary server is blacklisted on zen.spamhaus.org. Is there a way to un-blacklist these servers on the Qmail Toaster without removing zen.spamhaus.org from the blacklist file? Eric
