If you don't get a response back to the reply from a human inside of 24 hours, I'd reply again. It's also possible they're a tad busy at the moment… what with Convergence and all. Responses might be delayed, but if no reply in 24 hours, try again regardless. Aloha, Michael. -- Michael J

Re: [mailop] IPs blacklisted with Microsoft

Hi Michael, we also have a similar case ( SRX1402507373ID ) We acted like you suggested many times, the subnet also doesn't show any problems in SNDS and there were no JMRP mails. nevertheless, the robot didn't mitigate the issue and our manual response didn't trigger any action from "your"

Re: [mailop] mail.ru google and DMARC

I would add that SRS itself is fairly useless, it was never adopted as a spec, and it's unlikely many people are going to do anything special with it. There was never any method given for how one would validate SRS, so the most one could do would be to say trust the SRS of a domain if the SPF

Hi all. Does anyone have experience dealing with the SMTP response "550 5.7.1 Message rejected due to local policy" from iCloud / Apple? We have a few customers receiving these responses back, but so far it seems random. We can't tell if it is related to the local policy of the sending domain

ARC doesn't solve the problem either, because ARC requires trust to be established between all signers in the chain and receiver of the mesage. ARC doesn't provide any means to establish this trust. In short: ARC will only work with the whitelist of known forwarders and it doesn't contain any

Re: [mailop] About the Certified Senders Alliance

Hi David, I dare to disagree with your opinion that the sender is to blame. Gmail decides to alter the way the message is shown. This is misleading. I'd say either accept the message and show it completely, or if it's to large, then don't accept it at all on smtp level with a corresponding

SPF record is OK, see https://tools.ietf.org/html/rfc7208#section-3.3 mail.ru publishes strict DMARC policy (reject) to prevent spoofing. DMARC requires alignment between SPF authenticated domain and domain from RFC5322.From You perform SRS, so message you send is SPF-authenticated by your

By forcing Domain Alignment you would inevitably sacrifice the ability to send marketing mails for a huge amount of mom-and-pop shops. Even destroy the business model of a couple of ESPs. I don't argue against it, on my platform here, we even go the next step and try to force our customers to
