Outgoing messages get blocked (sometimes)

Hi,

I have a properly set up smtp server since my messages get sent from my
laptop from most networks. But ever on some LANs, and most recently at
my new job - so it's a problem, they get stuck in my outbox. (Later,
when the laptop is on a different LAN they get sent ok.) At the same
time, they do get sent if I switch to the locally provided smtp server.

So something somewhere is getting blocked. By what?

Many thanks in advance!

Your new job may have a corporate firewall that blocks outgoing SMTP
communications. Have you ever considered asking the network gods if they do
this?

Probably by outbound filtering on port 25 on the networks where you are a
guest. If your SMTP service that you are trying to reach allows it, you can
use another port. Port 587 is specified by RFC 2476; port 465 is another
common port. The point to remember: your SMTP service has to be configured
to listen on those ports, otherwise it won't work.

In general, you are better off checking with the network administrators how
they want you to access SMTP service. They may give their blessing, or they
may prefer that you use their SMTP servers.
