Resolved Dovecot Bug - Key to small

[Janko1000]

Hi,
Roundcube Imap Login is not possible because the following Error:

Error: Failed to initialize SSL server context: Can't load DH parameters: error:1408518A:SSL routines:ssl3_ctx_ctrl:dh key too small: user=<>

Workaround:

openssl dhparam -out /opt/psa/etc/dhparams1024.pem 4096
