I am using eudora as email client. i am not running pop3d on the linux Red Hat 6.2 so receiving mail is not possible as eudora can fetch mails from POP or IMAP servers only. The SMTP server is running so it should be able to send mails. If I try sending mail from the linux a/c in eudora, i am getting '550 <surindersingh@bflsoftware.com> ... Relaying denied' If i send/receive mails using telnet everything is okay ( receiving was possible due to Mikkel just few hours back). - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
