Hello,

Some time ago, KMail worked fine. I have several accounts, and whenever I sent from one, it would send everything correctly.

That was until I tried ticking the "Sticky" checkbox.

I have three email addresses. Here's what my setup looks like:
alec@foo.com (Default)
alec@bar.net
alec@baz.org

Now, whenever I send through any service, the "From:" line in the outbox is always "alec@foo.com", no matter what I do! Now with bar.net, it OK, because it's smart enough to correct the "From:" line. However, if I send it via baz.org, here's what it says:

Sending failed:
The server did not accept the sender address "alec@foo.com".
The server responded: "5.7.0 Sender address does not belong to logged in user {mp-us002}"
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.
The following transport was used:
BAZ

Does anyone have any way to fix this other that redoing all of my KMail configuration from scratch?

Thanks in advance!

Could you please paste the content of $(kde4-config --localprefix)/share/config/kmailrc with personal information removed?

Sure...

Here it is.

In the composer section, try removing the entry: sticky-transport=true
or setting it to false ( with KMail closed ).

Nope, doesn't help
I set it to false

Try removing everything under [Composer]

I did that, but it didn't help...

However, now that my composer window got reset, I found a (inconvenient) workaround - if I set the "From:" field visible in the composer, I can manually change the email address.

So the question is, how do I make each mail transport automatically associate itself with the corresponding email address?

Oops, that is a different setting altogether. KMail > Settings > Configure KMail. Identities > ( Select Identity ) > Modify > Advanced > Special Transport.

Oh, so I have to create a separate identity for each mail transport? I'll try that tomorrow morning...

Thank you!

I guess I've been using identities in KDE3 but didn't do that when using KDE4, so I guess it's been happening long before I used the Sticky...

Sorry for bothering you...
