I am facing a strange problem when I am trying to retrieve multipart mail from
POP server with attachments.
The task is to write a script which will retrieve mail with specific 'from'
field. Get the subject, body and attachments if any and reuse this info to send
mail with different format to ticketing system.
The global variable values I am expecting is:
msgList = [[msg1_subject,msg1_body,0],[msg2_subject,msg2_body,1]] and so on
attachmentList=[['none'],['attachname.txt','filename.pl']]
where none is no attachments.
But the result I am getting is:
msgList = [[msg1_subject,msg1_body,0],[msg2_subject,msg2_body,1]] and so on
attachmentList=[[none],['none', 'attachname.txt', 'filename.pl']]
An extra 'none' in the attachment list except for plain/text mails without
attachments.
I have tried a lot to figure out how to eliminate this but with no luck do far
:(
I know that some part is getting excluded from the condition, but I am unable
to figure out what is causing this.
Following is the function I wrote:
I am not an expert programmer hence my code is not clean, so pl. bear with me.
Thanks,
