Gmail's rejecting emails

[Antoine]

Hello,
When I send an email to Gmail, I get the following message:
SMTP error from remote mail server after end of data:
host gmail-smtp-in.l.google.com [74.125.133.26]:
550-5.7.1 [XXX.XXX.XXX.XXX 1] Our system has detected an unusual rate of
550-5.7.1 unsolicited mail originating from your IP address. To protect our
550-5.7.1 users from spam, mail sent from your IP address has been blocked.
550-5.7.1 Please visit

550 5.7.1 Bulk Email Senders Guidelines. o5si4694234wjo.117 - gsmtp

I check the SPF and DKIM records, but it seems correct.

How can I fix the problem?

Thank you so much!

your are experiencing a "soft block".
Contact your server provider and ask them to check for abusing neighbours... it is possible that the entire net-block is under a soft block.

It also can be from your server... may be a site/domain/user is abusing for SPAM.

Whats is output of

Code: Select all

exim -bpc

?

Hello,
Sure, I'll to the server provider about a "soft block".

The result for the exim -bpc is the following:

Code: Select all

ok the queue looks good.

Please check other threads and search "Email Deliverability factors" that entail proper rDNS, SPF, DKIM records.
Also check your IP and Domain for blacklists at mxtoolbox

You may also want to "rate limit" sending of email per domain/user. There are 2 threads for it in this forum.

So research is the key. But in the end, if you have a mailing list with high bounce ratio, you are always going to end in soft block.
