Update Ticket Takes over 10 seconds in 4.2.1

Hi,

There was some fix on V4.2.1 to force default mailer as PhhMailer (the most common mailing php liibrary).
I gues there is some issue using phpMailer in your case.

For information, you can retrieve previous behavior, just setting in parameters.php :or for ssl(this has an entrey in the user manual, just look for 'email')

I recorded ticket #1334 to have a look at possible phpMailer misconfiguration.
