fetchmail: OpenSSL reported: error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small
fetchmail: SSL connection failed.
fetchmail: socket error while fetching from email@example.com
fetchmail: Query status=2 (SOCKET)
This is specific to Sonic; fetchmail still works OK with imap.googlemail.com and outlook.office365.com. Web search turned up someone on Comcast with the same issue, and suggested that the default fetchmail settings were using an old SSL protocol incompatible with modern security settings. They were able to resolve the problem by adding 'ssl sslproto tls1', but that has no effect with Sonic. Any suggestions?
