[mailop] Gmail out of office replies

[Kieran Cooper via mailop]

Does anyone have any knowledge of how Gmail decides when to send an auto-reply?

I’m trying to test for a customer who has been missing auto replies. From what 
I can see so far, when I have an auto-reply set up, Gmail only seems to respond 
to some of the messages that arrive at the account. I’ve ruled out situations 
where the sender has already received an auto-reply that day. None of the 
senders that either work or don’t work are in the contacts.

It also looks as though Gmail sends these auto-replies to the return path 
address instead of either the From or Reply-To, which doesn’t seem to me like 
the right thing to do….

Any thoughts gratefully received!

Thanks
Kieran

Re: [mailop] Hotmail blacklist

[Kieran Cooper via mailop]

It’s an IP belonging to Amazon Web Services, and I know that Microsoft have 
been sniffy about those IPs recently because there are so many spammers using 
AWS servers now. You may be able to get MS to remove the block if you keep 
replying to the ticket until you reach a human, but you may find you need to 
change server….

[mailop] Barracuda IP listings

[Kieran Cooper via mailop]

A couple of our customers at SparkPost have started seeing widespread listings 
of multiple IP addresses on Barracuda’s blacklist and someone suggested that 
something might have gone wrong there overnight.

Does anyone have any info on what might be happening and, more importantly, 
whether they are already working to fix it?

Thanks
