I wanted to send a previously received email file (*.eml) as attachment to a correspondant.
I wrote my text (in Thunderbird) and attached the *.eml, but first I tested this email by mailing it to my own secondary address at a hosting provider.
Downloading my email from that secondary address I should have received my test, but it never arrived there, even though my local Thunderbird did report having succesfully sent it through gmail’s SMTP-server.
Sending that same test email with attached *.eml to my 2 other addresses through gmail’s SMTP-server worked just fine. I received those back without any problem at all.
Sending that test email back to me by way of my hosting provider’s SMTP-server also failed.
So it appears that my hosting provider’s POP3-server and SMTP-server both totally rejected my mail because it contained an attached *.eml file. Simply renaming that attached file to *.txt then restored normal operation.
Finally I sent the *.eml file to VirusTotal and got a “No Detection” response.
My hosting provider told me they’re waiting for an answer from their anti-spam supplier.
I haven’t the faintest idea who’s to blame.
Anybody?
