Problems sending mail to gmail.com
Hello all,
Last week google's gmail servers started to refuse messages sent from
our mailserver. We are small webhosting company and are also providing
email account for our customers (about 500 domains).
550-5.7.1 Our system has detected an unusual amount of unsolicited
550-5.7.1 mail originating from your IP address. To protect our
550-5.7.1 users from spam, mail sent from your IP address has been
550-5.7.1 rejected. Please visit
550-5.7.1 http://www.google.com/mail/help/bulk_mail.html to review
550 5.7.1 our Bulk Email Senders Guidelines. l38si175028nfc
I have checked our mail logs and from Sunday we have sent about 700
messages to gmail, most of this is just forwarded mail from customer's
mailboxes to their own gmail addresses, so I suppose they don't mark
it as spam. Mail volume our server is processing is about 20.000
messages a day.
I also contacted google using the contact form on the Bulk mail
webpage, but without success. Sometimes the mail goes through and
sometimes it gets rejected - depends on time of day and also on
destination email address (for 2 addresses it almost every time gets
delivered).
I have already searched google and find more people in the same
situation, all from end of September.
See http://groups.google.com.ag/groups/search?q=gmail+%22our+Bulk+Email+Senders+Guidelines.%22&qt_s=H%C4%BEada%C5%A5
Do you know what can we do against it? We already have reverse DNS
records for our servers. I'k now going to implement SPF as they
suggest, but only with "?all" as some customers don't use our servers
for outgoing mail.
