Since a recent update I cant send encrypted mail with thunderbird and the enigmail plugin anymore. Whenever I try to send the mail, and enter the passphrase for my key, I get the following error message by my mail client:
Send operation aborted.
USERID_HINT A22[...]00 [...] <[...]@[...].org>

What does that mean and why can't I send mails encrypted anymore?
I already checked all my keys, both the senders and the recievers keys are valid through 2019.
gpg -k | grep 16[...]00
pub 4096R/0x16[...]00 2014-06-13 [expires: 2019-06-12]
gpg -k | grep A3[...]86
pub 2048R/0xA3[...]86 2014-06-12 [expires: 2019-06-11]
I also checked my system clock and everything is allright.
I also did a gpg --refresh-keys
on the command line. Not sure what else I could try.
Versions:
gpg (GnuPG) 2.0.26
libgcrypt 1.6.1
thunderbird 31.0
enigmail 1.7
Any idea?
