Issue after last update

[Everex]

Hi,

We have an installation in a cluster with two nodes, and after updating the master node, the delivery in this node has stop working showing this error:

smg postfix/error[1003]: 9918A49F51: to=<xxxxxxx@yyyyyy.com>, relay=none, delay=1.7, delays=1.7/0/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)

The messages are queued in deferred mail.

We checked the pmg-smtp-filter service and is running, the port is responding, and don't see any error on the logs of this service.

As suggested in another threads, we increased the memory of the server, but does not solve the issue.

Someone have any suggestion that can help?

Thanks

Check the journal for errors from pmg-smtp-filter (or any other service) - check which process is listening on 10024 (`ss -tlnp`)

I hope this helps!

Hi Stoiko,

Thank you for your reply.

We can't find any error on the logs.

Anyway it seems to be working now, but we don't know why.

Regards.

If it happens again - feel free to respond with the logs - but glad it's working now!
