[toaster] Sending is so slow
Any tips on how to speed up sending, sending right now usually takes at least 10 seconds, we didnt put any reverse lookup checking on the qmail-smtpd/run. the only thing i guess its slowing it down is clamav and rblsmtpd list. but if we remove them we will have a barrage of spammers/viruses and then increases our queue to upto 5000 in an hour?? :(

There's a header for qmail-scanner that says the time it took to process the message "processed in x. secs".
[toaster] Yahoo Filtering and SMTP Routes
Hey All, Recently for some reason our customers have been complaining that mail forwarded or sent to their Yahoo accounts is being automatically deposited into their Bulk Mail folders. Contacting Yahoo! has been an uphill battle, and after numerous phone calls and e-mails to try and get to talk to someone with a clue we are giving up on them. Each of our SMTP servers has reverse DNS enabled and functioning correctly. We are on clean IPs, and none of the IPs are listed in any RBL or Blacklist. I would like to leave our current SMTP servers intact and simply have them forward any mail they receive from our clients to yet another SMTP server that we operate on an entirely separate network. This would only be temporary until we get Yahoo to actually tell us what is going on. How would you accomplish this with qmail? Thanks again, Peter

That will speed up lookups. Regards, Bill

Have they implemented SPF? http://spf.pobox.com/faq.html#forwarding I would like to leave our current SMTP servers intact and simply have them forward any mail they receive from our clients to yet another SMTP server that we operate on an entirely separate network.

How would you accomplish this with qmail? put: :ipoftempsmtpserver in /var/qmail/control/smtproutes and hup qmail-send (replacing ipoftempsmtpserver with the actual IP). And make sure that the new smtp server has your current smtp server setup as RELAYCLIENT. Regards, Bill
Re: [toaster] Yahoo Filtering and SMTP Routes
Bill, It seems that they have not implemented SPF as of yet, because we have SPF records on all of our domains. I will try the solution you posted and will get back to you guys. It seems that Yahoo does not have ANY contact information with their postmaster department, as customer care has no clue what an SMTP server even is!
