SMTP Fails to Authenticate
|Reported by:||BeDucky||Owned by:||axeld|
I've been using an HREV47259 VM inside VMware on a Windows 7 (64-bit) laptop as my main e-mail machine (via BEAM) since late May of 2014. Starting March 6, 2015 sending mail refused to work with the message "535 5.7.8 Error: authentication failed:". POP still works fine with the same user/password combination. (Plain password, unencrypted)
This reminded me that I had installed HREV48786 inside VirtualBox on a different computer in mid-January, and it had this same problem right from the start. In this case it was a 32-bit version of Windows Vista acting as the host. (I filed it under "figure this out when I find time," and it never made it back up to the top of my To Do list.)
In my trouble shooting, I did a fresh install of HREV48871 on two more machines inside VirtualBox: one a Win7-64 machine, the other a Manjaro Linux host. They both refuse to send mail in their Haiku VMs with the same error. SMTP works on both these machines both in the host OSes and in Linux-based virtual machines.
I've played around with all the settings that might have anything to do with networking, with no success. I'm stumped.
Between the last successful e-mail send and when SMTP gave up, I don't think I made any changes in to the host OS or VMware on the machine that used to work but stopped. I believe I did change the account password in that time period, but the old password was the one that refused to work in the first place on the Vista machine, so that seems unlikely to be the culprit. Even if it was, say, the special characters in the password, I tested it out with a dictionary word + a single number password...no dice. Also, I'd tried sending on both port 25 and 587, so that's not it. And it doesn't seem like it's a problem with the mail server or mail account in question, because I tried it out with more than one account and mail server. Plus, why would it work for POP, but not SMTP? Sigh.
I took one stab at trying to use Mail to send, but it died silently--as Mail is wont to do--and I don't think I ever got it to work even last year when BEAM worked without porblems, so I don't know if this is specific to the application.
