Hello,

About a week and a half ago, I received an email from one of the users in MilkyWay@home. He said he was having trouble receiving an email to reset his password even though our site confirmed the email was sent. After I tested the site using some dummy accounts, I found that not only was his account failing to receive emails, but ALL gmail accounts were rejecting our emails! I've tried looking into ways of having the PHP mail() function send to those accounts, but it's as if Gmail is completely ignoring all emails from our site. Every solution I've found on the internet has either failed to solve the problem or made it so that NO accounts can receive the password reset email. I've also received word from our user that only MilkyWay@home is giving him trouble with resetting his password. Is there anyone who can help with this problem?
Thank you in advance.

P.S. - After testing with a few other temporary emails, it seems that it isn't just gmail accounts that cannot receive the password reset email. It appears that any email that does not have a .edu cannot receive a password reset email.

It appears that any email that does not have a .edu cannot receive a password reset email.

Sounds like a change in policy of the institution. CPDN had a problem with these not going out and also with emails notifying people of posts they had subscribed to on their forums.

I can't remember the details but it was a security upgrade by the it staff at Oxford Uni that caused the problem.

Hope this give some clues as to where to start looking.

When I try receiving a password link, this is what I see in the mail log for our server:

May 22 14:31:12 milkyway3 sendmail[30076]: x4MIVCdl030076: from=boinc, size=545, class=0, nrcpts=1, msgid=<201905221831.x4MIVCdl030076@milkyway3.phys.rpi.edu>, relay=boinc@localhost

May 22 14:31:12 milkyway3 sm-mta[30079]: x4MIVCqZ030077: to=<rubegoldberg715@gmail.com>, ctladdr=<boinc@milkyway3.phys.rpi.edu> (1002/1002), delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=120783, relay=alt4.gmail-smtp-in.l.google.com. [108.177.127.26], dsn=4.0.0, stat=Deferred: Connection refused by alt4.gmail-smtp-in.l.google.com.

This seems like more of a security issue than a university problem. How can I change the securities to allow Google and other email providers to accept my password reset emails, and where can I find said configurations?

The SPF DNS record for rpi.edu is

v=spf1 ip4:128.113.2.225/28 ip4:128.113.1.201/29 ip4:128.113.26.109 -all

milkyway3.phys.rpi.edu however resolves to

128.113.126.52

Edit: It looks like your e-mails are being rejected by providers that check the SPF record (like GMail) as your sending IP is not listed on your DNS record. The IP address of your BOINC mail server needs adding to the DNS SPF record.
