Hello,

I have noticed this as well, but there were some changes as to how the Subject is generated since 1.2.1, so this problem with longer Subjects might be resolved in 1.2.2.

Regards.

This still seems to be a problem with Modoboa-1.17.0 and Postfix-autoreply-1.6.1, at least this happens reguarly at one of our modoboa servers (still running Debian "Stretch").

@tonioo Is this supposed to be fixed?
