[Bug 1013012] [NEW] regression with sendmail and Android clients

Public bug reported:

Something appear to be broken between the Android SSL library used by K-9 Mail (and the native Android "E-mail" client), and the 1.0.0 openssl in 12.04 as used by sendmail. I am seeing this error with K-9 Mail clients trying to talk to sendmail:
http://code.google.com/p/k9mail/issues/detail?id=3022

If I downgrade the sendmail-bin package to the version from Natty (which
uses openssl 0.9.8), everything is fine again. Oddly, the logs in K-9
Mail show successful post-SSL-handshake communication. It is extremely
unclear what is going on here.

Since nothing changed in the sendmail package between natty and precise,
I'm opening this against openssl. The problem could probably be anywhere
in openssl, sendmail, K-9 Mail, or the Android SSL libraries, but there
is at least a visible regression seen when changing from 0.9.8 to 1.0.0
on Ubuntu. :(

** Affects: openssl (Ubuntu)
     Importance: Undecided
         Status: New

** Summary changed:

- regression with sendmail
+ regression with sendmail and Android clients
