Postfix problem: send from yahoo webmail

[Pepere]

Hello,

after a lot of tests of sending/receiving emails, i think all is ok with this postfix configuration... With server webmail or with Outlook, all seems to be functional.

But if I try to send an email from a Yahoo or Hotmail webmail to an address present on my server, I've got a "Relay access denied".

All users must be able to send a mail from everywhere, with a local soft or with a webmail (server webmail, yahoo webmail, hotmail webmail or else).

Could you tell me what I've forgotten in my configuration ?

Thank you in advance

Is the domain you want to send a email to listed in /etc/postfix/local-host-names (I mean with and without www) ?

[Pepere]

Yes absolutly !!

After your message, I go into this file to verify if this domain was in. I saw all domains are mixed (not in right order). I place all domains in right order, first all domains with www then all domains without www.

Since I made tis modification, all emails are received and emails from external webmails too !!!

So thank you for your help

PS: I wish you all a Merry Chrismas

The order does not matter and ISPConfig will resort the domains. But maybe you had a typo in one domain, please check them in the ISPConfig interface, especially the co-domains.
