That's unusual for a "third-party email provider".

Well, I guess the HelpDesk person had a bad day.

If you absolutely have to send via their server,
definitely yes. Or maybe even use their webmail
service :->

P&T is by default blocking outgoing SMTP unless it's via
their own platform, which does antivirus and antispam
filtering and requires authentication.
This is self-protection, so as to avoid getting their IP
ranges onto blacklists and thereby getting into rather
serious trouble such as, for an extreme case, having the
entire AS blacklisted).
This is pretty standard for ISPs nowadays.
Do you have a good reason *not* sending through the P&T
platform?

Actually, normal residential customers do not have a
problem with this.
Professional customers which have opted for a static IP
or "pack pro" can get SMTP ports opened, but will then
have to see by themselves to keep their IP "clean" (i.e.
off blacklists).
