HI,

i am using postfix, when i try to send email to other domain, my emails are rejected from remote domain. in /var/log/maillog

Code:

host xxxxxxxxxxxx.com[xxx.xx.xx.xx] said: 503
    This mail server requires authentication when attempting to send to a
    non-local e-mail address. Please check your mail client settings or contact
    your administrator to verify that the domain or address is defined for this
    server. (in reply to RCPT TO command)

Can you post "postconf -n"?

That wasn't as helpful as I'd hoped.

Do you have permit_mynetworks in your smtpd_recipient_restrictions settings? IF not, you will need to add it.

It may be worth you showing us what you smtpd_recipient_restrictions are.

This is not set in default and so i didn't, i want to highlight another point, when i was using smtp.gmail.com as smarthost, i wasn't getting this error, since there is porblem in smtp.gmail.com, google removes the sender email to authenticated user, which is causing to reciver to unable view orignal sender, so i removed "smart host (relay)" configuration.

let me check smtpd_recipient_restrictions this, i will update you on this

thanks

Is host xxxxxxxxxxxx.com[xxx.xx.xx.xx] your server?

Ammad · 06-14-2009, 05:42 AM

yes, ..

is this can be problem of dynamic ip pool ( i am using dynamic ip pool on DSL modem). if yes then how remote smtp checks this, either i am using dnynamic or static IP pool.

thanks
