Error in mail queue

[devsecur]

If a user enters a invalid email address, such as name@domain.tld;name@domain.tld, the mail queue doesn't work properly. Mailer responses with 501 (Syntax error in parameters or arguments). Subsequent mails will no longer be sent.

Debug information:

{"date":"2018-09-20T12:38:14.968Z","module":"portal-mailer:utils","message":"- acknowledgeEvent()","delta":681,"level":"debug"} {"date":"2018-09-20T12:38:14.968Z","module":"portal-mailer:utils","message":{"code":"EENVELOPE","response":"501 Invalid command or cannot parse to address","responseCode":501,"command":"RCPT TO"},"delta":0,"level":"error"}

The email address verification could be improved by (?:[a-z0-9!#$%&'*+/=?^_{|}~-]+(?:.[a-z0-9!#$%&'+/=?^_`{|}~-]+)|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\[\x01-\x09\x0b\x0c\x0e-\x7f])")@(?:(?:[a-z0-9](?:[a-z0-9-][a-z0-9])?.)+a-z0-9?|[(?:(?:(2(5[0-5]|[0-4][0-9])|1[0-9][0-9]|[1-9]?[0-9])).){3}(?:(2(5[0-5]|[0-4][0-9])|1[0-9][0-9]|[1-9]?[0-9])|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\[\x01-\x09\x0b\x0c\x0e-\x7f])+)])` following RFC 5322

Thanks for reporting!

Fixed in 1.0.0.beta9 in the following ways:

• Better email checking in portal-api and portal-auth (both frontend and backend)
• 501 responses are being discarded, and portal-mailer continues to send out other mail
