[SM-USERS] HTML email locks up squirrelmail

[Bob C. <bo...@bo...>]

We have one contact who regularly sends HTML email which when viewed
causes squirrelmail to "lock up" for several minutes and won't respond at
all.  Viewing as plain text works fine.  Viewing the HTML in Thunderbird
works fine.  The headers contain:

MIME-Version: 1.0
Content-Type: multipart/related;
     boundary="----=_NextPart_000_0210_01C5024C.679ADEA0"
X-Priority: 3 (Normal)
X-MSMail-Priority: Normal
X-Mailer: Microsoft Outlook, Build 10.0.2616
X-MIMEOLE: Produced By Microsoft MimeOLE V6.00.2739.300

While I can provide a copy of one of the emails if needed, I'd prefer not
to send one to the list.

Is there a way to have squirrelmail handle malformed HTML emails more
gracefully?  I assume there must be some sort of problem with how Outlook
is forming these emails, but as Thunderbird is able to view them without
problem, we need a way to accept them in squirrelmail as well.
