Delayed OTPs for Websites to Email

Sean Bala shared this problem ago

Published

Hello - I'm a new user and I've been trying to use mailbox.org as my professional mail. I've noticed that when I try to get OPTs from websites, the e-mails don't come for about 10 minutes or so. It means that it delays me logging into sites for 10 to 15 minutes while I wait for the OTPs. Is this a common thing? Is there anything I can do in settings to not have this happen?

I'm also a new user and have experienced this as well. I think it *may* be a consequence of Grey Listing which is one of the antispam measures Mailbox use. When your account first receives an email from an unknown source it's rejected as most genuine servers will automatically send the message again a very short while later. I'm guessing that OTP servers don't resend due them perceiving the Mailbox rejection to be a security risk. The solution I've found is to request a further OTP as soon as you are able. The result is that one of them is then allowed through almost immediately. A bit of a faff I agree. Turning off Grey Listing is possible but it's not something I've done.

Hello Dave - Sorry I have not had a chance to reply sooner. I think your theory may be correct. I turned off Greylisting and I have noticed the OTPs seem to be coming in quicker. But I won't know for sure until I try a new site that may or may not have come into the mailbox.org servers. But I do notice less of a delay.

Out of caution, I've turned off Greylisting and the SMTP plausibility check. I've also set my spam settings to lenient and activated the junk folder. I plan on using this account pretty selectively so I'm not that worried about getting too many bad emails at the moment.
