I tested on Mxtoolbox, it shows my server isn’t an open relay.
@intelisense
Those are properly configured, I get a 10/10 on mail-tester dot com, as well as everything validated on mxtoolbox.
@TheBaldness
What type of error is it? Time-out, blocked, … ?
@TheBaldness
When opening the developer tools and going to the Network tab, are there errors? (refresh the page to be sure everything appears in the tab)
Hi, thank you for the answer, and sorry for the late reply :( …
I analysed the logs thoroughly, and I can confirm my SMTP server hasn’t sent any email aside the legitimate ones.
And u/voracitude 's answer confirmed my thoughts, being that the emails were sent from somewhere else.
I don’t think it’s that much unusual to use a “small” domain for spoofing: SMEs are “easy targets” usually, and if the recipient’s anti-spam isn’t configured properly then the attackers could benefit from a domain which may be small but has a good reputation.
