smtp error on sendmail but not on squirrelmail after opening port 587
 
I have a mail client that communicates with my dedicated server through ISP Verizon.net. Verizon recently blocked port 25 so my mail client can't communicate. I opened port 587 in sendmail.mc. Now when I log on the password for the email account is not recognized. Also, I get a bash no such directory when i query the /etc/password file. Does anyone have any idea where my password files might be located? Clearly the password is not a real issue as i can log in on squirrel mail.

Also, is there something amiss in this sendmail.mc snippet?

Change/add the following and rebuild your sendmail.conf file paying attention to the order(remember you need to listen on both 25 and 537);

CHANGE:

dnl DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea’)dnl

TO:

DAEMON_OPTIONS(`Port=587, Name=MSA, M=Ea’)dnl
DAEMON_OPTIONS(`Port=25, Name=MTA')dnl

RUN:
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

You should be good to go then....

Thanks, Forest.
I haven't had the chance to do this yet but it just looks right.

I made the changes but I am still getting a password error, Invalid username or password.
I even went into the server via the Ensim control panel and deleted the user then recreated it with to confirn the password but I still get the password error. I can't receive or send through the mailbox.

I can't find the /preferences/passwords file where, I think, the passwords are supposed to be stored.

I made the changes in sendmail.mc but I'm still getting a "invalid user id or password".
I went into the server via Ensim control panel to verify the password and user name. I even deleted the user and then recreated it to be certain of the password and username, but I still get the same error.

I think the password is supposed to be stored in a /preferences/passwords file but I can't find that file. Any clues?
