Roundcube having problems sending mail: Client host rejected: Access denied

[Paolo]

Hi guys,

I have recently set up a mail server by following this walkthrough: flurdy.com/docs/postfix

I have set up everything and worked through a few problems however most of it seems to work.

I am now having a problem with roundcube and not too sure how to fix it. These are the relevant lines from  /var/log/mail.log

Feb 17 21:40:37 mail postfix/smtpd[26333]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <localhost[127.0.0.1]>: Client host rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.MyDomain.com>
Feb 17 21:40:37 mail postfix/smtpd[26333]: disconnect from localhost[127.0.0.1]

- I have already checked and my ip has not been blacklisted
- This does work from another pc when I use thunderbird
- I have confirmed that port 25 is open to send mail from the ISP

I doubt it is any extra information but the error message reads:
"SMTP Error (554): Failed to add recipient "[email protected]" [email protected]"

Any assistance would be greatly appreciated.

Thanks

in your thunderbird settings have you enabled SMTP auth? if so then your need to do it in your roundcube config as well. look for $rcmail_config['smtp_user'] and $rcmail_config['smtp_pass'] in the main config file

Hi JohnDoh,

Thanks so much for that. A small detail overlooked has the power to cause countless hours of frustration.

Thanks for the help.
