I am installing my Postfix server. I am reading about the configuration options.
I see that there are many formats to use for lookups. I see for exanple this ... smtpd_tls_session_cache_database = btree:/var/lib/postfix/smtpd_scache smtp_tls_session_cache_database = btree:/var/lib/postfix/smtp_scache alias_maps = hash:/etc/aliases ... in one example doc. I can understand that there ARE diferences. I do not understand when to use which one. For example I have heard about the LMDB format from the OpenLDAP project. I hear that it is fast and lightweight and some persons say one of the best options. So is it best or even ok to do this? ... smtpd_tls_session_cache_database = lmdb:/var/lib/postfix/smtpd_scache smtp_tls_session_cache_database = lmdb:/var/lib/postfix/smtp_scache alias_maps = lmdb:/etc/aliases ... I am just wanting to know when to use which type? Arun
