[Enigmail] "Reply with template" failes with activated OpenPGP-Support for this identity

[powermax_123 at gmx.de]

Hello,

I would like to use the "Reply with template"-action when filtering mails. When an incoming mail matches the criteria of the filter, Thunderbird shall answer with a predefined template. It fails with the message "Senden der Nachricht fehlgeschlagen. Bitte überprüfen Sie Ihre Konten-Einstellungen und wiederholen Sie den Vorgang." (German Thunderbird) which says in English something like "Sending of message failed. Please check your account settings and retry". After deactivating OpenPGP-Support (Enigmail 0.95.6, gpg (GnuPG) 1.4.6) for this identity it works perfectly and the auto-reply is sent properly.

Is there a setting which prevents Thunderbird from auto-replying with activated OpenPGP-Support? Or does anybody has a solution for this problem?

Thank you in advance,

kind regards,
