Failur enotice that i didn't send

[MiquelT]

Hi,

We have recently installed plesk for linux 9.3, the OS is CentOS and the MTA is qmail.

Sometimes when we send a mail for example to [email protected] we recieve a Failure notice with the mail that we send but it says that it could not be send to some users, (notice that we only sent the mail to [email protected]).

It's like drigdon@sd-5266 is sending mails but we didn't have any user and any domain like sd-5266.

Here is an example (the mails and ip's are not the real ones):


Hi. This is the qmail-send program at plesk.somebusiness.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<[email protected]>:
Connected to 88.88.88.88 but sender was rejected.
Remote host said: 553 #5.1.8 Domain of sender address <drigdon@sd-5266> does not exist

<[email protected]>:
Sorry, I couldn't find any host named csbs.jcyl.es. (#5.1.2)

<[email protected]>:
Connected to 212.2.142.222 but sender was rejected.
Remote host said: 550 5.1.0 <drigdon@sd-5266> sender rejected

We didn't find anything in logs and don't know what's happening.

Thanks in advance.

Related errors from /usr/local/psa/var/log/maillog would be very useful for investigation.

I have seen a lot of mail in logs like this:

Feb 8 05:10:21 plesk2 qmail-remote-handlers[8188]: Handlers Filter before-remote for qmail started ...
Feb 8 05:10:21 plesk2 qmail-remote-handlers[8187]: from=jmkj@sd-5266
Feb 8 05:10:21 plesk2 qmail-remote-handlers[8187]: [email protected]
Feb 8 05:10:21 plesk2 qmail-remote-handlers[8187]: hook_dir = '/usr/local/psa/handlers/before-remote'


I don't know why jmkj@sd-5266 can send mails through our plesk, I have already tested that plesk is not an open relay, any kind of help would be very appreciated!

I don't see any errors here.

Try to rebuild mailsettings with

/usr/local/psa/admin/sbin/mchk --with-spam

Maybe it will help.

I have had a similar thing happening recently, very strange.
