I am in same situation as poster in that email incoming works but
sending does not. According to some stuff I have been reading if
your working through a POP account there are some issues because
of anti-spam software which needs some sort of work around.
Most of the work-arounds I read about did not seem very elegant
and so right now (as a iPhone nooby) I am just happy to be
receiving e-mail.
If nothing posts up on this forum I expect i will eventually call
earthlink tech and see what they suggest.
Any help appreciated.
