1. I am getting an error when trying to send email that says “553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)”

Make sure you are sending with SMTP Authentication turned on. See Email Settings to correctly configure your account.

2. I followed the directions on how to send mail (SMTP) but I'm still unable to send or I'm seeing errors

If your domain's SMTP settings do not work for you, it's possible your ISP is blocking common mail ports which are used to send email. In this case, you can use via SSL (see Email Settings to correctly configure your account) or use your ISP's SMTP server for sending mail.

3. Why do I keep receiving messages that say “**Message you sent blocked by our bulk email filter**”?

Spammers often send email setting the To and From headers as the same address (yours). The message you are seeing is what is normally bounced back to the spammer that sent the email letting them know it was blocked, but since your email address was forged as the From address, it's bouncing back to you. These messages are safe to ignore provided they are coming from (our spam filter).

      1. Specify the condition...: Select the radio button next to the setting that will create your desired auto response. Most people use an Autoresponder when they go on vacation, in this case, the default and first radio button next to “always respond” is the proper setting.

      2. Reply subject: Most people leave this as is. The “<request_subject>” text is a variable that will automatically get replaced by the subject of the email that was sent to you. If you want to add to the subject line of the auto respond email it is recommended that you add that text before or after the “<request_subject>” variable so the person that emails you knows what your auto reply was referring to.

    4. Limits area:

      1. Reply to the unique e-mail address not more than: It is recommended to set this to 1. Setting this to 1 will only respond to the same email address once and not keep autoresponding to the same person if they have to send you several messages. This also will better handle any mail lists or listserver lists that you are subscribed to.
