I have a client that claims that they have the correct mail settings yet they are unable to send mail. 2006-10-30 09:02:31 H=(legumex.com) [188.8.131.52] F=<Louise@legumex.com> rejected RCPT <firstname.lastname@example.org >: (legumex.com) [184.108.40.206] is currently not permitted to relay through this server. Perhaps you have not l ogged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client. 2006-10-30 09:06:02 no IP address found for host h66-244-210-156.bigpipeinc.com (during SMTP connection from (leg umex.com) [220.127.116.11]) BTW, I created a test account on the server and had no trouble sending mail thru the server. Any ideas?
