Can't send email

When I try to send email I get "Cannot send message using the server" I haven't had any real need to encrypt email, but I thought it might be good to have, plus I wanted to support your efforts if I could get this to work. This is happening to messages that I am trying to send unencrypted.

    Hi Charles,

    this is a standard smtp outgoing mail server error.

    Let's disable GPGMail for a second. Then please retry and see if the problem persists.

    • shut down
    • open finder
    • navigate to /Library/Mail/Bundles or ~/Library/Mail/Bundles and copy GPGMail.mailbundle to your desktop
    • now delete GPGMail.mailbundle from the original folder

    Restart mail and check in > Preferences if you still see GPGMail. It should be gone.

    All the best,

    Steve, Thanks for getting back to me. I think I did it right. GPGMail.mailbundle is on my desktop and one is in my trash. The problem still exists. when I open a mail document to be sent there is the little green box in the upper right that asks for my password. I clicked on the box so it greyed out s/mime and tried send it that way. I’ll try again by putting the password (leaving the green OpenPGP on) in. I get the same message either way. The smpt .comcast...(offline) message comes up.

    I restarted the computer twice and the green box disappeared so I guess I need to talk to Comcast?

    Hey Charles,

    if the green box disappears, it means GPGMail was not detected by (as expected since you removed it from the bundles folder).

    If the issue then persists it clearly means, this is not GPGTools related. If this is an IMAP account maybe removing and readding that account to can solve the issue. Or there could indeed be temporary server issues with the comcast SMTP servers. So why not ask them if they are aware of any.

    Feel free to keep us posted. And I hope you can find a solution for this account issue soon.
