On my old computer I discovered that some of my e-mails got lost in cyberspace, arrived in other people's junk folder or arrived very late (at the end of the day) because of the logo in the signature, which is a photograph. At the receiving end there was a scanning function which couldn't make any sense of it.
No problem anymore since I deleted it and only use letters.
And also, I could not send back client e-mails which contained social website logos (LinkedIn, Xing, Twitter, etc.). I had to delete them before sending my answer. Probably a security setting, but I never knew which one.
Were the social-network logos and the photograph hotlinked to in the HTML code of the e-mail or simply attached to it? My e-mail signature with all the social-networking links was the one that got marked as spam. As Rossana asks, are the outbound links themselves the issue?

Not at all! Your old signature had way too many links with little content, which is always a red flag.
It's good idea to check all email signatures/templates, etc. using a spam rating tool (out of the top of my head I only recall https://spamscorechecker.com
but there's a myriad of such sites on the web, just search for "spam rating" or "spam score" to find several sites).
Thanks Rossana! Yeah the old one had tons of links, but it was so much more fun!
I sent the offending message to SpamScoreChecker and it got back a Spam-Assassin score of -0.1/5 and listed the following broken rules:
* 0.0 FREEMAIL_FROM Sender email is commonly abused enduser mail provider (username[at]gmail.com)
* -0.0 NO_RELAYS Informational: message was not relayed via SMTP
* -0.1 DKIM_VALID_AU Message has a valid DKIM or DK signature from author's domain
* 0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
* -0.1 DKIM_VALID Message has at least one valid DKIM or DK signature
* 0.0 T_FILL_THIS_FORM_SHORT Fill in a short form with personal information

Also, emails marked as High Priority or Urgent are often recognized as spam by spam filters.
The same emails but not marked as HP or U are not recognized as spam
Thanks, Alexander! I sent this one from gmail and so I don't know of any option to mark messages as High Priority or Urgent. I don't see the priority markings that other people put on e-mail they send to me either.
Hopefully my e-mail contacts know that any e-mail from me is High Priority
