Bug#515503: exim4: dovecot_plain authenticator failed: 435 Unable to authenticate at present: authentication socket read error or premature eof

[Philipp Kolmann]

Package: exim4
Version: 4.69-9
Severity: normal

I have setup exim 4.69 with dovecot auth and saw this error when the password
was entered wrong:

2009-02-15 20:49:52 dovecot_login authenticator failed for [xxx]:
435 Unable to authenticate at present: authentication socket read error or
premature eof

I found that this bug is fixed for 4.70 here:

http://bugs.exim.org/show_bug.cgi?id=667

Would it be possible to add this fix to lenny for 5.0.1.

thanks
Philipp
