Tomas provided patch which was positively tested.
Re-proposed to 4.7
This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".
Found some issues in that patch. encodeHeaderBase64 function was not written to
handle 7bit charsets with escape sequences. It will work correctly only with
short unfolded headers.
Sorry. false alarm. Function does not know about iso-2022 escapes, but mbstring
extension knows them and splits string correctly.
I'm sorry for not addressing the issue in RHEL-4. As squirrelmail
is not scheduled for update in RHEL-4.9, I'm closing that bugzilla WONTFIX. If
you are still experiencing the issue with RHEL-5, feel free to reopen it
