Description

could not reliably reproduce, but experience error every now and then. might be
site-related. experienced in both linux and windows, os->all.
the mailserver in question is imap.web.de via imaps, using their own ca. i have
not yet imported the ca in this profile, not sure if related. will try that later.

grepping mozilla's sourcetree i discovered the message in
mozilla/security/manager/ssl/resources/locale/en-US/pipnss.properties.

the error pops up a message regardless of whether mailnews was the active window.

Changed product to PSM.

Error -12263 is "SSL received a record that exceeded the maximum permissible 
length."
Reporter, can you try a new profile to see if this might be a problem on the 
client side?

i have not yet had any luck reproducing this error, neither with a new profile
nor with my old one, it might also be serverside or related to my connection (my
imap.web.de connectivity is usually less than 100% reliable).
i'll update as soon as i encounter it again.

Marking works for me based on comment 3.

it seems web.de have migrated from selfsigned (trust.web.de) to thawte-signed
certificates. not sure if this really is related, but wfm is fine since the bug
did not show up again.
