SEA 4.5.1.0 - time of click vs. long urls

Agreed...

To not be able to control this is completely unacceptable.

What's worse is that the "quarantined" emails do not show up in the list of blocked emails that would otherwise be accessible by signing into the blocked messages portal like other quarantined / blocked mail.

Waiting on a response from level 2 / 3 support to figure out the best way to release messages that specifically were blocked due to the 990 character URL limit.  

It seems to be more common that they are quarantined when there is a large chain of emails / replies where Office 365 masks the already masked URLS which compounds the length of the URL's in signatures and other hyperlinks.

We are also experiencing this problem.  It has quadrupled the number of quarantined mails.

Having checked a few mails it seems that 990 is cumulative for the URLs in an email and not per URL.  One email I checked had 3x URLs, max length 751 which is a lot less than 990!

Sophos please fix this as it's usually a good rule to have enabled

Hi All,

Hi All,

Sophos Email Appliance v4.5.1.1 has been released. This includes the fix for SEA-1554 regarding ToC incorrectly quarantining emails.

Regards,

Can confirm that the firmware update to http://sea.sophos.com/rn/index.html 4.5.1.1 has resolved the problem of too many emails being quarantined with supposed long URLs.  Still to test whether the cumulative effect has been fixed.
