This is old with several known security holes.  You need to upgrade.

Still too old with known security holes.

We don't support SqWebMail.  You'll need to go here for that:

http://www.courier-mta.org/sqwebmail/

So consult your SMTP logs.  If sendmail is fast, then the problem
probably isn't anything to do with SquirrelMail.

So go look at why your SMTP server is so slow.

Can you install 1.4.13 and 1.4.19 on the same machine at the same
time, using the same configuration file?  If you can and 1.4.13 is
still faster, THEN you can start to figure out what changed.
Otherwise, I don't think it's a SquirrelMail problem.
