This way you can see exactly what is happening. There are two ways to implement tls on for smtp. Either a fully encrypted session, which plan9 does not support, or switching from a non-encrypted to an encrypted session if both ends agree (which plan9 does support). This is the HELO -v- EHLO greetingthe latter switches to TLS. you may need to ensure your plan9 supports tls1.2 if your smtp relays needs it, 9front has the fixes necessary. The labs distribution has the lines to confirm the TLS thumbprint of the relay commented out - it causes many problems in environments where the relay was implemenetd by several different servers. This may or may not be the case for your distro. the wiki has details of how to get and save the thumbprint. authentication of smtp is another issue, LOGIN and BASIC are very similar and quite insecure without TLS. NEGOIATE is a special microsoft protocol and is not supported, this leaves MD5 digest and machap which are chalange response and fairly secure. smtp tries to use tls but can be forced to talk insecurely by command line options. hope this helps, -Steve ^ permalink raw reply [flat|nested] 20+ messages in thread

Of course, thank you very much to pay attention to my problem. My provider doesn't support tls/ssl for mail service. They only support SMTP AUTH mechanism, which is >authentication of smtp is another issue, LOGIN and BASIC are very similar and quite >insecure without TLS. When I setup this new environment on my Ubuntu and macos, I was told its not secure, DO YOU WANT TO CONTINUE... like that. However, I have no choise to select, and said YES...

As I'm using ci5dell 9front terminal and macos/windows/ubuntu drawterm at random. When I use ci5dell 9front terminal, the hostowner is kokamoto, and mail authentication user is kokamoto%hera,eonet.ne.jp. I have secstore password for kokamoto, but not for kokamoto%hera.eonet.ne.jp. When I use drawterm, the hostowner is glenda (this is 9front system:-), and mail authentication user is kokamoto%hera.eonet.ne.jp. In this case, I have neither glenda's nor kokamoto%hera.eonet.ne.jp's secstore password. However, in both case, I was asked from factoum to enter the password, then I enter the paswword for kokamoto%hera.eonet.ne.jp user's password, which is given from our provider. At present, I have no success in both case. I'll try further again and again using different situations. Kenji ^ permalink raw reply [flat|nested] 20+ messages in thread
