Can't send email to one gmail address, but can to another

Support
1

NethServer Version: 7.9.2009
Module: Postfix 2.31.3

domain: mrlistersir com
IMAP email using Thunderbird email reader.

My ISP changed my static ip address from a static address to a permanently leased DHCP provided address. I had to change the ethernet configuration to DHCP.

I host my own mail server and edited the A records accordingly.

After these changes, I can no longer send email to my primary gmail account (gillowwiles.henry@gmail com). However, I can send email to other gmail accounts that I use (gillowwh@osu.edu).

I have attached the log file for the last attempt to send email to the gillowwiles.henry account. I am not knowledgeable to know what I am looking for in the log files.

I hate it when things work for a long time then stop working. I never remember how I set things up the first time.

Any idea where to start looking?

How-to: email_protection_resources [NethServer Wiki].

Try DKIM, DMARC, SPF, check MX, SMTP

Sorry, my native language is English. Thanks for the consideration, though.
I do have a follow-up question.
The day before the changes made by my ISP, everything was working just as you would expect. The only changes were the new IP address and the updated a records. What do you think happened to cause the change in my email behavior? It sounds to me like the action taken by my ISP might have broken something, but I’m a bit out of my comfort zone here.

In my SPF record (TXT record), I specifed my IP address:

v=spf1 a:ns-1.toto.org mx:mail.toto.org ip4:1.2.3.4/32 ~all

Thanks for your help. I ended up editing the DKIM and SPF records and everything is working now. I don’t know what changed on my ISP’s end, but their migration wasn’t as seamless as they promised.

Hi @henry,

Glad it worked.
