Email Handling and vBulletin Cloud – vBulletin Community Forum

Posted by jpluimers on 2023/08/25

For my link archive: [Wayback/Archive] Email Handling and vBulletin Cloud – vBulletin Community Forum.

  • Asking your end users to white list your email address and the Sendgrid IP (167.89.58.99) can help alleviate the issues.

I didn’t know the above but bumped into an issue because I didn’t know a supplier had moved to vBulletin Cloud, my account password stopped being accepted and my account password reset messages would not arrive.

So I wrote this as part of a mail to sort this out, and it was confirmed to be correct:

Then I re-checked a few connection refusals that appeared close to the password reset tries. Not sure if this a pattern, but a few of them had this:
2022-02-20T19:41:42.999415+01:00 snap sendmail[24314]: NOQUEUE: connect from o1678958x99.outbound-mail.sendgrid.net [167.89.58.99]
2022-02-20T19:41:43.015958+01:00 snap sendmail[24314]: NOQUEUE: dns 99.58.89.167.bl.spamcop.net. => 127.0.0.2

2022-02-20T19:42:29.527789+01:00 snap sendmail[23814]: 21KIeTfo023814: engine10.uptimerobot.com [69.162.124.231] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
From the linked page I got to https://www.spamcop.net/w3m?action=blcheck&ip=167.89.58.99 indicating

167.89.58.99 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 13 hours.

Causes of listing
  • System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Express-delisting is not available

Listing History

In the past 44.4 days, it has been listed 12 times for a total of 13.3 days

Can you check if the forum software uses sendgrid?

The confirmation linked to the first post in this blog entry on how to whitelist the SendGrid outgoing IP-address.

One thing I wonder: why does SendGrid use a single outgoing IP-address? If it gets blacklisted, many of their clients have problems.

Anyway: before adding the entry to my whitelist, the problem had resolved itself, and the blacklist entries were done:
