Yahoo Mail outgoing mail server

[aklein]

Hello Kostya,

let me thank you first for your great app. I recently bougth the pro version to support your development, because i think your doing a great job and Aqua Mail is the best mail app out there.

I have an issue with my outgoing yahoo mail server. I know this is not the first time you have problems with Yahoo, but I cant figure out a solution. When I try to send a mail from the app, it tells me:

Login-Error: 535 5.7.0 (#MBR1212) Incorrect username or password.

My configuration is:
smtp.mail.yahoo.com
SSL(strict), 465

I am sure, that username and password are correct, I checkt them both several times. I also found a post on you website saying, that there was a problem with Yahoo smtp last week. Your workaround did not work for me.
Do you have any idea what I could try to solve my problem.

Thanks a lot.
André

Andre,

Yes, those are the right settings but Yahoo is "famous" for authentication failures and other weird error codes.

Don't take my word for it:

https://www.google.com/search?q=yahoo+MBR1212

Things to try:

- Going to Yahoo web mail for this account, logging out, closing the browser, and logging into web mail again

- Changing the outgoing server from smtp.mail.yahoo.com to android.smtp.yahoo.com (same SSL and port)

The latter will get you a different actual server out of all the load-balanced ones.
 
On my system I get:

$ nslookup smtp.mail.yahoo.com
Server:      192.168.1.1
Address:   192.168.1.1#53

Non-authoritative answer:
smtp.mail.yahoo.com   canonical name = smtp.mail.global.gm0.yahoodns.net.
smtp.mail.global.gm0.yahoodns.net   canonical name = fo-smtp.mail.eu.am0.yahoodns.net.
fo-smtp.mail.eu.am0.yahoodns.net   canonical name = smtp.mail.eu.am0.yahoodns.net.
Name:   smtp.mail.eu.am0.yahoodns.net
Address: 188.125.69.59

$ nslookup android.smtp.mail.yahoo.com
Server:      192.168.1.1
Address:   192.168.1.1#53

Non-authoritative answer:
android.smtp.mail.yahoo.com   canonical name = star.smtp.mail.yahoo.com.
star.smtp.mail.yahoo.com   canonical name = star.smtp.mail.global.gm0.yahoodns.net.
star.smtp.mail.global.gm0.yahoodns.net   canonical name = fo-star.smtp.mail.eu.am0.yahoodns.net.

Hello Kostya,

thank you so much for your answer. I tried your "log out trick", but it did not work for me. What I did then was deleting my yahoo mail from aquamail and recreating it with the standard incoming and outgoing server. That worked for me, even though it is the exact same server and credentials. I did not try the outgoing server you suggested, but I will keep it in mind, if yahoo is going crazy the next time :-D.

Thanks a lot,
André

I have the exact same problem.  Mine will work fine on WiFi.  I only get that error over Sprint cellular data connections.  Go Figure that one.....

Yahoo's mail servers are load-balanced (naturally). You may be hitting a bad one because of this.

If you add "android." in front of server names, you'll get different ones (stock Android Email uses "android.", K9 doesn't, go figure).

To do this, long press the account -> account setup -> Manual.

Change "imap.mail.yahoo.com" to "android.imap.mail.yahoo.com" and/or "smtp.mail.yahoo.com" to "android.smtp.mail.yahoo.com".

I have this problem of setup Yahoo mail in my Galaxy S5 as well because I have 2 step login verification enable and Yahoo Mail does do not support the 2 step login verification. I have it run now and it is easy forward to fix. 

If you have 2 step login verification enabled you will need to create an application password for programs.
To create an application password go to your Yahoo inbox, then click the Gear and select Account Info.
In the left side navigation click Account Security.
Scroll down to the App Passwords section, type in the name of the mail program, then click Generate password (App passwords are set-and-forget passwords that Yahoo create to use with apps that are not compatible with 2 step verification).

@MinhTran: So, if I understand your message correctly, you succeeded using 2-step login verification with Aquamail. Right?

Just in case, - the alternative is to re-enable password-based login which Yahoo calls "allow access to less secure mail apps", as described by Kostya here:

Yes, with 2 step verification. I did it yesterday and it worked but it gave me error afterward. I login in Yahoo account on my computer and re-generated new password and go back to my phone to re-setup. It is working so far. I think the error may cause when I generated 2 passwords at the same time for two diff. app's. The second time I selected for Android app only. It's worth a try. I have 4 emails addresses so I love Aqua Mail --I have Pro version. I will post up again if I have problem. Go to this site for detail:
