Re: Problems sending mail to yahoo?
Barry Shein wrote: Is it just us or are there general problems with sending email to yahoo in the past few weeks? Our queues to them are backed up though they drain slowly. I know that Yahoo does greylisting, and we often have a large queue backup as a result of mailing lists with a lot of @yahoo.com addresses. As long as you keep retrying I find that they do eventually get through. Between greylisting and sender callback verification, it seems that overall email delivery is increasing in latency and decreasing in reliability.

And compared to them, we're tiny. Don't know if it's widespread, but it appears you are not the only one so blessed. We've seen this before too but this week it has been different. Every single host that relays email on our network has these in the queue. Now a couple of them do mailing lists and such so I could see it happening but a couple of them don't do anything high volume at all. For some of them some mail goes through but only some of the time. It seems like if we hit the right MX machine it works and other times it does not. We tried going around them by sending mail over to an employee's personal mail server (which does nearly no volume at all) but even it is blocked probably 1/2 the time. I'm not sure what is going on but given all this I can't believe it is just normal. We filled out one of those forms but just got back a response that said it wasn't happening but if it was we should see their best practices URL. Only problem is we actually do everything on their list (including both DomainKeys and DKIM).

Ditto for broken OOO autoresponders and foolish AV software backscatter. I see this 'not greylisting' and we are a fairly tiny operation (I had about 20k outbound emails last week) and don't allow people to autoforward email from our servers. I find that yahoo.com destined mail stays in the queue for about 48 hours, with a 1,1,2,4,4,4,4,etc... hour retry. As I tend to peak at a couple of hundred mail in the queue when things get busy, it's not a problem, but can see where it would be for larger operators. -- Eric Esslinger Information Services Manager Fayetteville Public Utilities Fayetteville, TN 37334 Phone: 931-433-1522x165 Fax: 931-433-0646 [EMAIL PROTECTED] begin:vcard fn:Eric Esslinger n:Esslinger;Eric org:Fayetteville Public Utilities;Telecom adr:;;408 College Street, West;Fayetteville;TN;37334;USA email;internet:[EMAIL PROTECTED] title:Information Services Manager tel;work:931-433-1522x165 tel;fax:931-433-0646 x-mozilla-html:FALSE url:http://www.fpu-tn.com version:2.1 end:vcard
