iOS 14.5.1 (18E212): mail client of iPhone incorrectly automatically appends “.com” extension to a pdf file extension while sending a forwarded mail- send mail fails.
Issue is occurring on iOS 14.4, 14.4.2, and also on 14.5.1.
As per the mail server logs generated, the SMTP client is appending some url at end of pdf file name which is ending with ".com".
Thus the generated error as reported in this feedback is thus clearly on account of iPhone mail client, which is suo-moto appending the .com extension to a pdf extension file in the mail attachment.
The send mail failure happens on all networks when there are pdf attachments in a mail which has been received and is now being forwarded.
The Mail sending does not fail with mails without attachments or a new mail composed on the iPhone itself.
The same mail with pdf attachments gets sent successfully from other than iOS device like a MacBook or Windows computer mail client (like native Apple Mail or Microsoft Outlook) using same IMAP account (which is failing in iOS) on all types of networks. No such error occurs when connecting through Gmail or outlook.com accounts. The error occurs only with IMAP type accounts and only on iOS device.
This indicates that there is no issue with the affected IMAP mail account or the imap mail servers or network connection, but instead the issue is caused by a bug in iOS.
The error message is -
“Cannot Send Mail.
The connection to the outgoing server ’smtp.mail.gov.in’ failed. Additional Outgoing Mail Servers can be configured for Mail accounts in Settings > Accounts & Passwords.”
