The source of the mail looks okay to me (I verified that from a different machine than the one I sent the mail). You may want to check your browser or proxy?It’s correct in the plain-text version of the mail.

If you feel the need to insert a redirection link, I’d very much appreciate it if you would post the full link in the text version, as well as the href.

I sent the mail from Gmail. I checked the source using the Gmail "show original" mode (which displays a mail in plain text including headers and all MIME sections) from a different computer, but I cannot find that URL. I cannot check an email copy that the mailing list server sent back because Gmail automatically de-dup emails, which is annoying, but I think it's unlikely that my machine is infected from evidences I've seen so far. Maybe a mail transfer agent in between Gmail to you inserted the link? I'd appreciate if you can forward the mail including headers to me.

I think I found the problem: https://opia.illinois.edu/content/targeted-attack-protection-tuning UIUC is apparently rewriting HTML links in emails to redirect through urldefense.proofpoint.com. This is visible in my version of Rui's email. On Wed, May 27, 2015 at 9:36 AM, Rui Ueyama <ruiu at google.com> wrote:> I sent the mail from Gmail.

But I suspect it's the mailing list's servers rather than your computer, Rui. This might be related: https://opia.illinois.edu/content/targeted-attack-protection-tuning Messing with people's messages is not great though, no matter how well-intentioned. I bet they'd break signatures, for a start. Tim.
