    I'm unable to send any email on my iphone 4s. i already had this problem on the iphone 4 but it seems to persist despite getting a new phone. i know that my username and password is correct...

    anyone else got this error before?

    Is this via iCloud? Saw the same error yesterday... had to enter a different address from the SMTP server rather than the default iCloud smtp that it gave me. smtp.me.com rather than smtp-7.mobile.me.com (or something similar) worked in my case.

    Just because you can receive means nothing because you can specify a different server, username and password for outgoing mail.

    Same problem here: receive/no send

    All settings same as with iPhone 4.

    if it's icloud - I had this issue throughout the beta testing period - it'll go away after a while - not ideal, but nothing you can do about it - try submitting a bug report to apple.

    Found a fix for mine...

    When going from 4 to 4S, you have to enter 2 passwords:

    Incoming Mail Server is one the first mail account page, the one where you can toggle the account On or Off.

    Scroll down to Outgoing Mail Server .... see the arrow to the right?

    Clicking it brings you to a SMPT page, where you can activate one or more outgoing servers by clicking on, for instance:


    and entering your password again for that account.

    Account will be verified & voila! :D

    It isn't working for me.. :(

    i input host name as smtp.att.yahoo.com
    user name and pass as my email id and pass
    set SSL to on,
    authentication to password
    and server port to 587

    still doesn't work..

    My solution was to keep deleting it, and adding it again, it worked after a couple times. and that's what yahoo suggests to do. keep trying

    try this

    Ok I think I may have a solution..this is what I tried and it worked.

    go to :settings
    then Mail,Contacts,Calenders
    then to the email account thats unable to send
    then at the bottom ADVANCED
    then near the bottom there should be a S/MIME turn it on

    this is what I did and it worked !


    By the way I was having problems with my hotmail account. I never had a problem with my Gmail

    I was getting this message with my osu.edu email account (who goes through outlook)...this was happening about 3 times a week and would come and go

    Here's how I fixed it:

    When in your mail settings, for the outgoing server, even though it says username/password is optional, type your username and password in.

    I haven't had an issue since (about 3 weeks)

    i was able to solve this with iphone 4, iOS 5.1.1 by re-entering my hotmail account password on the following screen:

    "Settings" -->
    "Mail, Contacts, Calendars" -->
    <select affected mail account, e.g. myname@hotmail.com> -->
    select SMTP server (scroll down to "Outgoing Mail Server" section; the SMTP server for hotmail is 'smtp.live.com') -->
    select SMTP server again (under "Primary Server" section at top; this should be marked as 'On') -->
    on this screen, delete whatever is entered under "Password" and re-enter your login password for the account; when you click "Done" at the top of the keyboard, it will show a series of checkmarks next to each field to let you know the outgoing smtp server configuration is correct. -->

    send a test message from your account to another account to verify that all is well.
