Hi all, I'm using my university's SMTP server for sending mail, which I connect to directly from Mutt (i.e., I have no MTA or pseudo-MTA installed). The mail server is running MS Exchange.
This always works just fine, but right now I'm at a conference, and all of a sudden, using the exact same config files for Mutt, I cannot send mail. I get the following error: SMTP session failed: 500 unrecognized command Running Mutt with -d3 gives the following in .muttdebug0: Using default SMTP port 25 [2011-08-29 15:34:06] Looking up mailer.gwdg.de...

Even though I have been using it for almost two years and the instructions on configuring smtp for the mail server explicitly say to enable it. Like I said, I'm at a conference, so I'm not on my usual network. However, I'm connecting through Eduroam, which is a world-wide roaming network, which I also use when I'm at my home university. Besides, I can send mail fine from my iPad... I have very few smtp-related settings in .muttrc. Just smtp_url and smtp_pass, and ssl_force_tls, that's it. Anyone have any idea why Mutt may have trouble sending mail? Personally, I don't have a clue and I'm not sure where to look for further helpful info... I'd be grateful for any hints or tips.
