    Anyone else have a problem with the extreme amount of time it takes to send a single email? If your emails are sending quickly, what settings are you using for your SMTP server? Its slow if I am on EDGE or wireless, using multiple accounts. On occasion it will send fast, but most of the time its slow...

    On WiFi sending mail is almost instantaneous for me. On EDGE it depends on the size of the email, how many replies are below, etc, but it's never a super long time. I'm using all the default settings when I set it up.

    Not the case here, but it is a bit faster on WiFi. Are you using POP or IMAP? Do you know if you are connecting to an exchange server or something unix based?

    If your SMTP server is using SSL on port 25 (via the STARTTLS command), you need to change the TCP port on your iPhone. I was having the same issue with mine, took around 3 minutes to send a single email.

    Turns out, my iPhone was trying to connect to some port other than 25, and then timing out after 3 minutes and trying again on port 25. Once it tried port 25, it took only 1 or 2 seconds to send the mail.

    Change your server port number in the mail settings section of the settings application. On version 1.0.2 you have to add ":25" to the name of your SMTP server. So if it is "someserver.com" change it to "someserver.com:25". For version 1.1.1 you can change the port number in the advanced settings screen.

    This really helped

    This was a great tip! It fixed my slow outgoing email problem :)
    This is on an iphone 5S ios7.
    The automatic settings for my outgoing email server were incorrect. Moreover IOS7 wouldn't let me change the outgoing server settings since it was the primary for this email. So I had to delete the account and re enter everything.
    This is NBD since it is an IMAP account. Don't know what I would do if it was a POP account.

    The moral here is to check your settings against a known working email client!
