The variable TLS_PROTOCOL was unset. So I tried to set it to TLS1.2, but I get the same error. ##NAME: TLS_PROTOCOL:0 # # TLS_PROTOCOL sets the protocol version. The possible versions are: # # OpenSSL: # # SSL3 - SSLv3 # SSL23 - all protocols (including TLS 1.x protocols) # TLS1 - TLS1 # TLSv1.1 - TLS1.1 # TLSv1.2 - TLS1.2 # # Leave it unset to use any protocol except SSL 2. TLS_PROTOCOL=TLS1.2 My Debian is "uptodate". Yesterday I already checked it with aptitude update && aptitude safe-upgrade. The version of courier-imap-ssl is 4.15-1.6. I ve already reinstalled courier*. I dont know what is broken. Two weeks ago I just had to renew my certificates, same procedure as every year. But this time I get the error. ------------------------------------------------------------------------------ _______________________________________________ Courier-imap mailing list Courier-imap@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-imap
