At seeming random times, a Mailhost object becomes corrupted and does not allow the sending of mail. I get an error that states "integer expected" -- see full traceback below.

Enter the MailHost and press 'Change' to re-save the settings. Or upgrade to 2.6.1. In fact, do both. :)

According to the source code it looks like the port number is becoming corrupted. To solve the problem, all I have to do is open the Mailhost object and save it. Strange.

Are you sure it gets to be a string again? That should only happen if you upgrade from 2.5.x or import an 2.5.x exported mailhost. For some reason, the port number was changed from an int to a string in 2.5.1, and this got reverted in 2.6.0 without anybody noticing.:) In 2.6.1 it should be an integer, but will not fail if it is a string.
