Hi, After upgrading courier-imap, I cannot connect anymore: every time I try starting TLS I get the error: couriertls: /usr/local/ssl/crt/combined/mail.cs.ait.ac.th.pem: error:0906D06C:PEM routines:PEM_read_bio:no start line The certificate file has not changed a bit. I am at lost to what I can try now. Help is very welcome. TIA, Olivier
