Description Mattias Andrée 2016-02-22 08:58:44 UTC 
When I try to sign a message with my GPG key,
and claws-mail is running under X11-forwarding
(over ssh), I get the error message

  Could not queue message for sending:

  Signature failed: Data signing failed, Line passed to IPC too long

This appears before I am given the chance to
enter my passphrase.

Seems a gpg configuration problem, specifically the text mode pinentry¹.

A quick Google search shows you probably need to set an environment variable:

export GPG_TTY=$(tty)

In any case, nothing to do with Claws Mail, hence closing.

HTH,
