Swift Mailer doesn't mail to Yahoo and Hotmail

It seems that I'm unable to send emails to Yahoo and Hotmail accounts.

Gmail account is alright, though.

Any ideas on why this is happening?

I'm just trying the tutorial "Sending a basic email" at http://www.swiftmailer.org/wikidocs/v3/tutorials/basic
But I'm using sendmail instead of SMTP.

I'm running my setup on OSX, 10.5, behind a router, if that makes any difference

Hello, it does work.. I send many emails to those domains.
Is your server blacklisted?

Not sure about being blacklisted.

Shouldn't be since I'm only sending emails to my own email accounts.

Does blacklisted mean that the emails won't get sent, or the emails will be classified as spam?

Are you sending emails from your own computer? If you are, are you connecting to your ISP's SMTP server or using localhost? Using localhost will almost certainly get you in spam blockers since dynamic IP addresses are almost always blacklisted by default.

There are a whole bunch of things to check here too:

I'm indeed sending emails using localhost, so it's safe to say that any 192.168.xx.xx addresses will be blacklisted also.

No wonder I had no trouble while testing the site on a server connected directly to cable and not behind a router.

Thanks.

Being behind a router doesn't make a difference. Your public facing IP is what the SMTP server sees. If your IP that is issued by your ISP is not static then you'll be blacklisted. Even some "static" IP addresses get blacklisted frequently if they are in a range which the blacklist maintainer is seeing trouble patterns with. Huge chunks of Amazon EC2 IP addresses have been blacklisted before. The blacklist maintainer does this to make it clear that whoever is responsible to leasing the addresses needs to moderate the behaviour on them.

My test emails finally arrived on Yahoo mail, 22 hours later.

Thanks for the link, it's very useful.
