Hi Eric,

You are probably right, I guess a change between 9.1 and 9.3 on this point. I just downgraded to emacs 26.1 and to org-mode 9.1 because I also noticed that org-export-head https://github.com/itf/org-export-head i.e. the org blog exporter that I am using does not work with org-mode 9.3, unfortunately, and Ivan has no time to adapt this tool to the last release of org-mode. That's too bad...

Best wishes,

Jo.

I wonder whether you have too many \\ (or even any) in this and the
similar replace-string that comes later? Why do you have these at all?
The string argument to both replace-match and replace-string [1] is not
a regexp so [] do not mean anything special.

Have you tried with just "gnus:[Gmail]/..."?

Footnotes:
[1] and according to the documentation, replace-string should only be
used interactively and you should use replace-match instead.
