[Dovecot] pop3 CAPA STLS and stupid clients

Hello,

is it possible to disable the announcment of STLS in the CAPA-command for the pop3-daemon? I want to support pop3s, but only at port 995, not through the STLS on port 110. The reason for this is that some clients have problems with this and strange errors appear (e.g. older imap-libs) although they don't seem to have a problem with pop3s through port 995.

Regards Marten
