Unreliable outlook sending

[maxelcat]

Hi all

Running xp pro with outlook2000. I find that I can receive emails no problem. When connected to my router (hard wired) I can send no problem.  When I go to my office, and connect via wireless I find that only about 1 in 6 or 1 in 10 of the emails I send arrive. I receive ok.

I have tried to see if there is a pattern but I can't really detect one.

Would value any pointers/suggestions

Thanks

Any traffic blocking going on at the Office ? ?
This could be a firewall or other web management software...

I know this is porbably a "Thick" question, but where should I look - would it be in the wireless router that the office has installed?

Thanks for reply - appreciate it
