We have been using secure contact form for quite some time now, but recently we are getting issues with the mails.
Sometimes when people use the form the e-mail simply does not reach our inbox. But when trying with a test mail, everything works just fine. Some of the mails arent send, while others are. We already tried with captcha turned of, at first it seemed to work but a few days later the problem persisted.
I would like some advise/tips that might help find and/or solve this issue.
