tmptitle when processing emails

Hello,

everytime I try to process new emails it creates a new post titled tmptitle and nothing else.

The email I’m using is @gmail.com (don’t know if it helps)

I read somewhere that I could fix it by increasing the WP_MEMORY_LIMIT so I set it to 512M (it was 256M) but to be honest I don’t even know where I can check if I have 512M available.

Hope someone can help me
