I am unable to email via Craigslist with any of the craigslist apps or even by going to craigslist.org via Safari. As a hobby/side line of making extra income, I frequently buy used lawn equipment and appliances from people on Craigslist. I fix these items and sell them and sometimes donate if a friend etc needs something. So, that all out of the way, the problem I am having is that all of a sudden when i try to respond to an ad or listing via email, my emails never go through. I dont get any kind of error message, my phone doesnt lock up or anything of the sort. The email simply just seems to vanish, never sends, doesnt show up in my sent folder. I have tried using all sorts of craigslist iPhone apps, tried to use Safari on my iPhone, used Yahoo email, Google mail, Exchange. Craigslist lets me log into my account, lets me post items for sale etc, lets me receive email from other people responding to my postings on Craigslist so I dont believe they have blocked me in any way. I am simply stumped as to what is going on. I dont know if i have inadvertently triggered something by updating or changing a setting on my iPhone or what. I started going through my sent fodlers and this all seems to have begun on October 25th. just very strange. I have searched the internet and found nothing in regards to anyone having similar issues.
