Problem sending email in one title

We have a problem with sending emails (new submission, add reviewer, add journal manager) but only (!) in one title on our platform
In other journals - sending works correctly.
Our version,hmm 2.4.5
Where should i look for a solution?

Hi @karwas,

This is probably related to your server’s DMARC settings or something similar. The only way to debug these that I’m aware of is to get access to your mail server’s delivery logs to see why the messages are being rejected.
