    Default RCPT TO:<> 501 Syntax error in parameters or arguments

    Zen Cart 1.3.8a, smtpauth, Windows 2003, IIS, MailEnable, new install, very few customizations. www.stdtime.com/store.

    When some people attempt to order, they get an SMTP error (with no details). The mail server logs show the error below.

    RCPT TO:<> 501 Syntax error in parameters or arguments

    Evidently, the "to" email address is empty in RCPT TO. But again, this only happens with some people. Most people who order are fine.

    All my email options have an email address. Any idea which field is empty?

    Regards,

    Bump. Any input on this issue? It looks like it's not supplying the "to" email address during some orders.

    I can't replicate the unique problem you're experiencing.
    Perhaps you have invalid "extra" email address fields set for the admin copies?
    Or, if you turn off all your switches to send copies to yourself, does the problem disappear?
    What pattern have you seen with the cases which have allegedly failed?
    Does the customer actually receive the email?
    What's showing in the email archive? (assuming you've turned it on and installed the addon to allow you to view it) Which emails *are* sent vs *not*?
    What addons do you have installed?

    When did this suddenly start to be a problem for you?

    Default Problem with the contact us email

    Hi,
    I've been searching all day for a solution to this smtp error:

    -------------------
    SMTP -> get_lines(): $data was ""
    SMTP -> get_lines(): $str is "220 web20.3essentials.com "
    SMTP -> get_lines(): $data is "220 web20.3essentials.com "
    SMTP -> FROM SERVER: 220 web20.3essentials.com
    -------------------
    SMTP -> get_lines(): $data was "" SMTP -> get_lines(): $str is "250-web20.3essentials.com Hello [127.0.0.1] "
    SMTP -> get_lines(): $data is "250-web20.3essentials.com Hello [127.0.0.1] "
    -------------------
    SMTP -> get_lines(): $data was "250-web20.3essentials.com Hello [127.0.0.1] "
    SMTP -> get_lines(): $str is "250-SIZE 14680064 "
    SMTP -> get_lines(): $data is "250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 "
    -------------------
    SMTP -> get_lines(): $data was "250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 "
    SMTP -> get_lines(): $str is "250-AUTH LOGIN CRAM-MD5 "
    SMTP -> get_lines(): $data is "250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 250-AUTH LOGIN CRAM-MD5 "
    -------------------
    SMTP -> get_lines(): $data was "250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 250-AUTH LOGIN CRAM-MD5 "
    SMTP -> get_lines(): $str is "250 OK "
    SMTP -> get_lines(): $data is "250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 250-AUTH LOGIN CRAM-MD5 250 OK "
    SMTP -> FROM SERVER: 250-web20.3essentials.com Hello [127.0.0.1] 250-SIZE 14680064 250-AUTH LOGIN CRAM-MD5 250 OK

    -------------------
    SMTP -> get_lines(): $data was ""

    SMTP -> get_lines(): $data is "235 Authentication successful "
    -------------------
    SMTP -> get_lines(): $data was ""
    SMTP -> get_lines(): $str is "250 OK Sender ok "
    SMTP -> get_lines(): $data is "250 OK Sender ok "
    SMTP -> FROM SERVER: 250 OK Sender ok
    -------------------
    SMTP -> get_lines(): $data was ""
    SMTP -> get_lines(): $str is "501 Syntax error. Syntax:{RCPT TO:[SIZE=msgSize]} "
    SMTP -> get_lines(): $data is "501 Syntax error. Syntax:{RCPT TO:[SIZE=msgSize]} "
    SMTP -> FROM SERVER: 501 Syntax error. Syntax:{RCPT TO:
    [SIZE=msgSize]}
    SMTP -> ERROR: RCPT not accepted from server: 501 Syntax error. Syntax:{RCPT TO:[SIZE=msgSize]}
    -------------------
    SMTP -> get_lines(): $data was ""
    SMTP -> get_lines(): $str is "250 OK "
    SMTP


    As you can see, the rcpt variable is not understood by the smtp server. I can send an email fine from the admin environment and can also send a newsletter fine.

    SMTP authentication does NOT seem to be the problem. I believe that the rcpt email is either incomplete or missing, but I can find no errors in my configuration.

    Several people have had this problem, but there seems to be do definitive solution.

    Thanks,
    Marty

    Default Re: RCPT TO:<> 501 Syntax error in parameters or arguments

    Tech support at my ISP states that the log shows:

    RCPT TO:<>

    Which is why the server is not accepting it. The script is passing an empty variable, even though it is set correctly in admin/config

    So, in Admin->Configuration->Email Options, what do you have set for the following:

    - Email Address (Displayed to Contact you)
    - Email Address (Sent FROM)
    - Set "Contact Us" Email Dropdown List

    NOTE: The Contact-Us dropdown entries MUST follow the prescribed format as described next to the input box. Not following that format will cause the email addressing to break.
    And not entering ONLY an email address (ie: fred@domain.com) in either of the other entries I mentioned will also cause email delivery problems globally.
