For the past month or so, I've been getting sporadic "Relay Error - Check Recipient List" messages when sending mail through my ISP's smtp server. The volume of these is increasing daily. It doesn't matter which pop email account I'm sending from - I get it using my ISP email address as well as other email accounts I have set up to send through this server. I managed to capture some smtp logs and something caught my eye - there is an extra CR (CRCRLF) following the recipient's email address. The log shows: 0[7b1b00]: SMTP entering state: 4 0[7b1b00]: SMTP Send: MAIL FROM:<[EMAIL PROTECTED]> 0[7b1b00]: SMTP entering state: 0 0[7b1b00]: SMTP Response: 250 <[EMAIL PROTECTED]>... Sender ok 0[7b1b00]: SMTP entering state: 6 0[7b1b00]: SMTP Send: RCPT TO:<[EMAIL PROTECTED]> 0[7b1b00]: SMTP entering state: 0 0[7b1b00]: SMTP Response: 550 <[EMAIL PROTECTED]>... Relay error - See http://www.domain.com/support_relayerror.html 0[7b1b00]: SMTP entering state: 7 The CRCRLF shows up after each <email@address>. Is mozilla adding this, or is it coming from somewhere else? I'm wondering if this might be causing the problem with my ISP giving me the bad recipient list error message. I've gotten the error trying to send to a bunch of different recipients at different domains. Some new messages, some replies. The error and CRCRLF is always the same, though. Is this a bug? Yes/No/Maybe?
