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.

Hello, thank you for your answer and sorry for the late reply.

I took some time analyzing my SMTP server logs, and it contains 100% legit outgoing traffic. And no successful SSH connection for weeks on the server so it can’t have been erased.
u/voracity confirms my thoughts as well. I think the issue is outside and unrelated to my server. And the e-mail address in question seems to have leaked from several places according to haveibeenpwned (the password is safe though).

@voracitude Thank you very much! This confirms my worries, not much can be done…

@wintermute_oregon
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.

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)

@[email protected] If you are looking for a phone with an huge battery, CAT phones (“CAT” from “Caterpillar” - yeah, they make phones) can be interesting for you. You can choose one of them depending on how much you’re ready to spend on it.

Otherwise, Fairphone 3 and 4 are good options as you can replace their battery when it dies, and they provide spare ones for as long as thhe device is supported (they support them usually much longer than most phones from other manufacturers, so far). I own a Fairphone 4 and it’s very good. But maybe too expensive if it isn’t your main internet/entertainment device.

@[email protected] Oh, you’re right! I didn’t know about that. My bad 😄
