email sending problems

T

Toby

when sending emails to certain adresses, i recieve an
error stating the email couldn't be sent because the
adress was rejected by the server. it says "server error
550." it's really annoying because then i have to go
into a webmail and send it out that way. i would say
about 50% of my outgoing mail will not send because of
this reason. any advice?

thank you
