Checking configuration after changing IP address of smtp server
Greetings,

I manage the email server for the nexaima.net domain on a VPS.
Everything has ran, SPF included, without problems for a few years.

Today the VPS provider had to change the IP address of that server.
Due to a series of misunderstandings and errors which is really not
relevant to discuss, I did not knew in time about this change. I only
realized something had gone wrong _after_ email stopped going and
coming.

Right now I have updated the DNS records of nexaima.net to point to
the new IP address of the VPS. Now I can connect via IMAP and see
email that arrived right before the switch, but:

- cannot send email
- email sent to nexaima.net doesn't arrive
- am not sure if SPF is still configured properly

part of the problem which I only realized a few minutes ago is that I
still have to change the content of /etc/resolv.conf, because the DNS
servers too changed IP address. I am waiting from the VPS provider to
tell me which nameservers I should
use now. The question for the list are:

1) can you please help me to check what the situation is now, ie send
a test email to mfioretti @ nexaima.net and check in your logs what
happens to it?
2) can you please check if the SPF configuration for nexaima.net is
still correct?

TIA,
Marco

Your MX is set to a.mx.nexaima.net on 213.179.193.33. Your DNS appears to
have been updated about an hour ago.

> - cannot send email

Can't help with that. It's between you and your VPS provider, I should
imagine.

> - email sent to nexaima.net doesn't arrive

213.179.193.33 refuses connections on port 25. It's not a mail server...

> - am not sure if SPF is still configured properly

nexaima.net has no SPF record, so no - it isn't.

In future, you might find it easier to run your own DNS server. It's not
difficult.

Mail cannot be delivered to that address because your listed MX is not an MX.

It isn't.

Vic,
thanks for the prompt answer. However:

> 213.179.193.33 refuses connections on port 25. It's not a mail server...

I had temporarily stopped it to check something. May you please try
again? Thanks

It's broken.

There is a postfix server there (apparently), but it is *very* slow to
respond initially, and claims my address has a "Bad address syntax".
