Sorry for the repeat, my employer's firewall seems to play havoc if I try and edit my messages, so I'll try posting the whole thing at once:
OK, after getting fed up with the increase in spam I've seen since the holidays on my ISP account, I've decided to turn on my freebie email addresses for webmail.mydomain.com. I thought I set things up correctly earlier in the day, but I continually get the Unknown user or password incorrect message from SquirrelMail when I try to login.... I've sent an email to alias1.mydomain.com, which points to the mailbox mailbox1.
I've tried using alias1 as the username, and I've tried mailbox1, but both give me the unknown username error. Is this a problem with SquirrelMail specifically, a problem related to the (possibly pending) new webmail system, or am I just an idiot?
Addendum: I sent a message to the alias in question ~ half hour ago, and it has not bounced back yet (for what that's worth...)
