Extra intermediate certificate when using ssl_alt_cert
I just added an ECDSA certificate to my mail server using ssl_alt_cert (the RSA certificate is specified by ssl_cert), both certificate files contain the certificate and a single intermediate (which currently happens to be the same intermediate from Let?s Encrypt).
When connecting to the server using either RSA or ECDSA ciphers, the server sends the proper certificate, but also sends two

ssl_cipher_list
Hi,
I have noticed the 'ssl_cipher_list' directive in the 1.0-test
snapshots which is not in 0.99. It's default value seems to be
"all:!low". However, this would not be compatible with openssl's
cipher listing format. Thus, I would vote to change it's format to be
openssl compatible. To be compatible, it has to be changed to
"ALL:!LOW" (just upercased in

dovecotservice and increase filelimit

Deploying Diffie-Hellman for TLS
I have been reading up on TLS and Dovecot and came across this URL:
https://www.weakdh.org/sysadmin.html which recommended these settings
for Dovecot. I would like to know if they are correct? Some much
documentation on the web is pure garbage.

These changes should be made in /etc/dovecot.conf

Auth process sometimes stop responding after upgrade
Hi all;
I've upgraded a ring of dovecot directors from 2.2.15 to 2.2.36. After the upgrade I've got

2015, uptime of the server today is more than two months. It is a
virtual machine in a data center, debian 7 / reiserfs, 'dovecot -n'
