Description
Someone on gmail is complaining about getting mails delayed by as much as a day from geos mailing list.
Looking at the mail logs, it seems we are being dinged on sending plain text mail. So I suspect any email to an @gmail.com address may be dinged delayed because of this.
The log shows
Your email has been rate limited because DKIM authentication didn't 421-4.7.30 pass for this message. Gmail requires all bulk email senders to 421-4.7.30 authenticate with DKIM. 421-4.7.30 421-4.7.30 Your email has been rate limited because this message wasn't sent 421-4.7.29 over a TLS connection. Gmail requires all bulk email senders to use 421-4.7.29 TLS/SSL for SMTP connections
