The error states that your first line is malformed, and it is.  As the error says you need to make sure your first line begins with "Mailservername:".  So, in your case:

set mail_pre "Mailservername: abcd@autoex.ae:Exms20!7@exmail.emirates.net.ae\n"

I'm guessing based on what you tried.  Note: EEM Tcl does NOT do encrypted SMTP.  Only applets support that.

hello joe,

Thank you for your response...!

I still confused as you suggested in my first line

imagine my mail server name is exmail.emirates.net.ae and username is abcd@autoex.ae  and password is Exms20!7 in this criteria the below configuration is true?

set mail_pre "Mailservername: abcd@autoex.ae:Exms20!7@exmail.emirates.net.ae\n

-------------------------

I think i cant do it applets because my username have @ , am i right joe?

[Joe Clarke]

Yes, this is correct.

hello joe,

i have tried the below configuration, unfortunately still i face the same error "%HA_EM-6-LOG: MAILIPSla.tcl: wrong 1st line format."

set mail_pre "Mailservername: abcd@autoex.ae:Exms20!7@exmail.emirates.net.ae\n

am i doing wrong?. any guess.?

[CSCO12798688]

is it possible to do encrypted smtp in any other way?, i mean other than tcl 

[Joe Clarke · Accepted solution]

No, only applets can do encrypted SMTP.  But applets do not support '@' in usernames.  Your only other alternative is to setup a mail server that either doesn't require encryption or can use a simpler username.

[CSCO12798688]

Thank you joe.

You must not have a space between Mailservername: and the username.  You must have a space there.  It needs to be:

set mail_pre "Mailservername: abcd@autoex.ae:Exms20!7@exmail.emirates.net.ae\n"
