bug#31990: 26.1; Stuck in loop trying to send bug report

Hi,

        While trying to send a bug report with long lines I
        got stuck in a loop.

        Here's what the *Messages* contained:

Sending...
Mark set
Fix continuation lines? (y or n) n
Send anyway? (y or n) y
Fix continuation lines? (y or n) n
Send anyway? (y or n) y
Fix continuation lines? (y or n) n
Send anyway? (y or n) y
Fix continuation lines? (y or n) n
Send anyway? (y or n) y
Fix continuation lines? (y or n) n
Send anyway? (y or n) y
Quit


        The SMTP trace log contained:

220 smtp.mail.yahoo.com ESMTP ready
250-smtp422.mail.bf1.yahoo.com Hello localhost.localdomain [73.16.70.190])
250-PIPELINING
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-SIZE 41697280
250 STARTTLS
220 2.0.0 Ready to start TLS
250-smtp422.mail.bf1.yahoo.com Hello localhost.localdomain [73.16.70.190])
250-PIPELINING
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-SIZE 41697280
250 AUTH PLAIN LOGIN XOAUTH2 OAUTHBEARER XYMCOOKIE
MAIL FROM:<nyc4bos@aol.com> SIZE=5830
450 Requested mail action not taken: mailbox unavailable
QUIT
221 Service Closing transmission


    As you can see, the STARTTLS capability is available
    (resultant code "250 STARTTLS") but a STARTTLS command was
    NOT subsequently issued (oppurtunistically).

    Not sure whether or not this was related to the loop responding
    to sending a bug report with long lines and selecting "n" to
    NOT fix up and "y" to send anyway.

    Thanks.
