Hi everyone,

I got the latest PLESK ONYX with everything updated. Its running on ubuntu 16.04 server.

I found out that I cant recieve and send mails, not sure why, but still troubleshooting

I tried to fix it with the plesk mail repair command but it didnt found any problems.

This is the error that can be found in the maillog:
Dec 30 11:31:35 malta1254 master[24069]: fatal: master_spawn: exec /usr/lib/postfix/sbin/y: No such file or directory
Dec 30 11:31:36 malta1254 postfix/master[23222]: warning: process /usr/lib/postfix/sbin/y pid 24069 exit status 1

Dec 30 11:32:37 malta1254 postfix/master[23222]: warning: /usr/lib/postfix/sbin/y: bad command startup -- throttling

Anyone any ideas? Got a simillar configuration working pretty good on the second dedicated server.

Thank you all for helping!

 

I have the same problem, I can receive emails however, just can't send.

 

xgenesis, not sure but I think I found the problem to my case... some misconfiguration in the master.cf

Could you please post here your /etc/postfix/master.cf file?
