Mail.app works for me also really well. Have a Setup of 4 Pop-Accounts and 1 IMAP-Account, that's hosted with from the school windows-server. Even that one works perfectly well.|
A few years ago, I had sometimes also the problem that I had to reenter the password etc. Later I found out it was a configuration error on my part. You have to be really careful to input your account data accurately.
And then there are some servers, that require you first to check your email and then they let you send your mail. That is quite a strange behaviour nowadays, where we have SSL to check your access rights.
You should also check your Keychain, if there there double-entries of the same account. That can happen and be a problem. Delete them, start Mail.app and re-enter the password and save it to the keychain.
