Copied just to format it.
You did something to your master.cf can you not see the Warnings? always good to do a backup of config files before messing around with them.
Whatever you did to your master.cf is sending it in a loop. Fix your parameters and it will go away and allow your postfix to start.
Yeah. Iâm not familiar with the code but starting with 3Gi head room, no way this should run out of memory. And the warnings are new? They donât appear in the output above.
@joe might be able to tell you a safe reinstall path. I canât.
Is this procmail command correct? It could also interfere with the action of the postfix.
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
Looked right. I only know because I had a problem with it so I double checked. Thatâs what mine is.
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
And I made some changes recommended by Postfix SMTP relay and access control.
Thank you for your information.
Considering this time when everyone helped me to try to find the problem but, as it continues to make it impossible to read and receive the emails, I will reinstall Webmin / Virtualmin and the 06 active domains.
My thanks to all.
With the withdrawal of the external command in Postfix Mail Server - Local Delivery ⊠/usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
Iâm getting the emails normally. The submission is not yet resolved.
I donât know what you mean by âwithdrawal ofâ. Do you mean you switched back to the default Postfix deliver agent?
If so, youâre losing all the Virtualmin mail handling features (spam/AV scanning, forwarding, auto-responders, etc.).
Are you on an ARM system? ARM is not a supported architecture, we donât have repos ARM, so if you installed on ARM, youâre missing procmail-wrapper. Though Ilia has posted a procmail-wrapper package for ARM a couple of times in the forum.
I deleted the external command line from Postfix and the local emails (system) started to arrive.
I disabled that I could to try to find the problem, including disabling the vmâs of the websites. Now, after reactivating, I only have clamAV disabled. The external procmail command is active. POSTFIX is and remains enabled.
That doesnât reduce anything. It makes it much more resource intensive on a server that processes more than a few mails a day.
I donât think youâve posted any logs. We have to see logs to know why something is failing.
/var/log/maillog and possibly journalctl -fu postfix (you have to start tailing the journal before you try to restart postfix, so we see whatever is relevant to it starting and shutting down).
$ journalctl -fu postfix

I really appreciate the effort to solve this problem but, I go to my ISP to reinstall the webmin that for me is very complete and deserves my fight. Hopefully at some point in the future Iâll find out where the error occurred. So I can start the new week with all the websites and emails active.
Best regards.
