Thank you all for this great info. I have postie 1.4.2 on WP 3.1.3, network. On all of the networked sites postie is running fine but on one site no. I went through all things above mentioned. Symptoms are; when picking up email using the ‘run postie’ button I get a server error. After that if I go to posts, the last post is there but with ‘tmptitle’ for title and content is only ‘tmpPost’. Same thing when running on auto. Strange that it would not work on just one site (3). I suspect maybe a plugin but don’t want to turn off all of them. Guess I will have to give that a try.
