Nethserver 8 update breaks mail

Hi all, ive completed the updates on 2 seperate servers running Rocky linux and both have ended up with issues.

I’m currently running mail 1.5.4 and the new update takes it to 1.6.1, when i run it then i have issues with outlook connecting which brings an error on sending with the encryption on the port.
this is using port 587 starttls (i have tried SSL and auto still the same error)

No email is allowed to enter the system, getting an error in the mail log smtp 451 4.7.1 try again on all, have tried disabling the filter (through the gui) greylist is not active

the only way to get it all to work is to revert back to a snapshot before i upgraded.

Any thoughts on this would be greatly appreciated

thanks

The temporary SMTP error code 451 may be caused by Rspamd/ClamAV or Dovecot/LDAP services that are not working properly.

Please try to capture the relevant Postfix log lines from System logs — NS8 documentation or from the node system journal.

Are the issues the same for both servers?

Hi Davidep, thanks for coming back to me, yep same errors on both servers.

for today i have updated rocky linux seperately and also update netserver core 11/04/2025 and at present the issues arent there.

ill start updating the apps, in this case.

crowsec 1.0.12 - 1.0.13
imapsync 1.0.4 - 1.1.0
mail 1.5.4 - 1.6.1
webtop 1.2.1 - 1.3.0

Though i am thinking its the mail update that keeps breaking

thanks
