Title: 504 5.5.2 <pdev10>: Helo command rejected: need fully-qualified hostname: gmail
Post by: devnullius on 18. December 2014., 01:40:49

From my devnullius gmail.com I started to receive these errors more and more:
504 5.5.2 <pdev10>: Helo command rejected: need fully-qualified hostname

It's not very often, but often enough.

At first, I blamed it on other email servers but today I sent an email to someone, got a reply, replied to it and 504 5.5.2 :( A fresh email to the same email address also returned this :(

I have no idea where to look for it. I just log in to devnullius account and do my thing. Google does not show much relevance either...

Anyone an idea? *any* idea? :)

Might be it! But could not happen with webinterface for gmail... I'll check the details next time this happens :s

Thanks!

The IP seems odd to me :/
Does this only happens when using a mail client, or also with gmail's web interface?

Yeah I've been looking at that too but might not have looked good enough (IP).

It's from the web interface and I don't think I have extensions running that can cause this... I use BetterGmail but that plays with CSS. I don't use BrandMyMail on devnullius account. So that's out too. Only thing left is an extension that monitors (and reads out) new emails in certain labels.

Sigh...

Almost makes you think I have a hidden webserver running... But no 10-network is known to me - fully 192.168 here! :)

It's not every email. Just a few of them - but a bit too much of them to be irrelevant :/
