HI guys, i am running ubuntu 18.04 and ISPConfig 3.1 I have a problem with 1 email account from 1 Domain only and i get the following error: Code: Jul 28 22:44:00 server4 postfix/smtpd[326]: NOQUEUE: reject: RCPT from st43p00im-zteg10073401.me.com[17.58.63.181]: 451 4.3.5 <[email protected]>: Recipient address rejected: Server configuration problem; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<st43p00im-zteg10073401.me.com> Do you have any idea what can the problem be? the other emails seem to work well. thanks a lot for your help
That infoaddress seems to be wrong somehow. Compare how it is set up differently to the other working e-mail boxes. The e-mail setup tutorial linked to in my signature tells a bit on how to debug e-mail problems.
The issue is at the info@ address, if I understand it right then you don't host that info address? In this case, there is nothing that you can do as its a problem on the recipient's side.
Hi, Thanks a lot for your kind help. I host the info@ address and i found a solution in delete the email with ispconfig and then set up the email again, now everything is working.
