I'm new to Roundcube. I've used the bcc field successfully many times. Both today and yesterday I tried to send an email to myself with 50 bcc addresses with two attachments, 1 @ 33kb, 1 @ 28 kb. The email arrives in my inbox, no error messages but no one else gets it. I've seen postings about a php setting but I don't know where or what that is. HELP!!! :-\
have you checked the smtp server logs to see the message was sent correctly? and things like spam filters on the recipient side?
