[Dovecot] Force STARTTLS on port 143 for !internalnetwork
Hi! How can I force users which are connecting from OUTSIDE our newtworks to user STARTTLS on Port 143? Right now we resort to IMAPS on port 993, but an additional STARTTLS enabled login on the default port would make things easier! -- Ralf Hildebrandt Gesch?ftsbereich IT | Abteilung Netzwerk Charit? - Universit?tsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt at charite.de | http://www.charite.de
