breaking out of mutt on locked up connect?

[Tom Fowle]

Greetings
As fastmail is having "dos" attacks, sometimes mutt (1.5.23) hangs on the
"connecting to mail.messagingengine.com" statement.
Nothing I can think of to try will break the locked state short of
rebooting.
Other than telling me to upgrade, which intimmidates me,is there a solution?
Thanks
