Package: fetchmail
Version: 6.3.26-3
Severity: important

 After updating libssl1.1 to version 1.1.0f-4
 fetchmail refuse to connect by IMAP to a set of my mailboxes
 with the error: 

localhost fetchmail[3635]: OpenSSL reported: error:14171102:SSL 
routines:tls_process_server_hello:unsupported protocol
localhost fetchmail[3635]: SSL connection failed.

 I found that the similar error (#871918) was reported to
 libssl1.1 package but it was closed.

 First of all I think that such changes in library as 
 disabling TLS 1.0 and 1.1 must be reported in apt-listchanges

 I resolved this issue by adding option "sslproto 'TLS1'"
 in fetchmailrc.

 So my second point is following. Is it correct to remove
 the obsolete non-secure protocols without even a hint to a reasons?
 Is my connection now is more secure? What should I do as user of mailbox?
 If I send a mail to the system administrator with diagnostic like
 in above of this letter it will be rejected because it is my problem.
 Is it possible to add to the error the version of protocol from 
 the server side with mark in case of insecurity? 

 Thank you.
Yu.
